Project Topic: Design and Implementation of Electrically Tunable Filter on Thin-Films Enabled Engineered Substrate

Project Description: To miniaturize communication systems, great efforts have been spent on developing tunable RF passives. Fully electrically miniaturized tunable RF passives have been implemented with the integration of both ferromagnetic and ferroelectric thin films directly into the individual specific design. A strategy to improve the ferromagnetic resonance frequency (FMR) of Permalloy to over 6GHz and an electrically tuning method of equivalent permeability for Permalloy with DC magnetic field generated by applied DC current have been developed.  A novel engineered substrate implemented with embedded multi-layer Permalloy and lead zirconate titonate (PZT) thin film patterns has been recently investigated and proposed, the substrate has high and DC current tunable permeability and DC voltage tunable permittivity. Miniaturized frequency agile arbitrary RF components could be developed with the proposed electrically tunable engineered substrate combined with state-of-the-art RF design techniques. In this research, it is planned to combine the above two techniques to design, fabricate, and test an electrically tunable filter with the goal of optimizing the resonator structure and the engineered substrate to improve tuning range and performance.

Project Topic: Design and Development of a Bluetooth-based Continuous Blood Pressure Monitoring Device

Project Description: High blood pressure (BP) or hypertension (HTN) is a common condition which can lead to serious cardiovascular complications if left uncontrolled. The condition requires continuous monitoring of BP and electrical activity of heart (Electrocardiography- ECG) which the existing bulky instruments fail to provide without hindering the patient’s daily activities. This work proposes a home monitoring cuff-less and hassle-free blood pressure wrist-based device that derives BP from photoplethysmography (PPG) and ECG signals, and uses Bluetooth for real-time wireless communication with a smartphone. A user can wear this device as a watch/wristband/armband and the signals are transmitted to a mobile device or computer, possibly connected to a cloud for further analyses and computing. Development of a customized Bluetooth circuit with a printed 2.4-Ghz antenna is crucial for continuous monitoring. Quarter wave patch antenna will be developed and characterized and later incorporated on a flexible substrate.

Project Topic: Wearable Sensors for Elbow Flexion Monitoring

Project Description: Monitoring elbow joint kinematics after a medical procedure is critical for maximizing/accelerating rehabilitation and preventing future injuries. The most common technologies used to date for monitoring elbow joint kinematics include 3D/2D motion computing cameras and goniometers. However, these technologies are not portable—making it hard for them to capture valuable data in a standard individual’s daily environment. The proposed project seeks to resolve these issues through the development of a lightweight, flexible, and low-cost wearable joint sensor that is embroidered into a textile. These wearable sensors will leverage the principles of magnetic flux in order to measure the flexion of the elbow with high-accuracy and reliability. Additionally, novel methods for powering these wearable sensors are being explored as a way to remove the need for bulky batteries.

Project Topic: Calibration Procedure for Cryogenic Noise Measurements

Project Description: Accurate calibration of cryogenic noise measurements has been a long standing challenge due to uncertainties associated with thermal gradients along the path between the reference noise source and the device under test (DUT). One approach to address this problem is to perform the measurement using a tunnel junction noise source, which can be operated at the base temperature and whose noise spectrum is well described by basic physical expressions. However, for this technique to work, the insertion loss between the intrinsic tunnel junction and the input of the amplifier must be known. The goal of this research is to develop a methodology for this loss to be systematically determined. A two-tiered VNA calibration procedure will be developed to allow for determination of the gain of each component along the path from the input of the DUT to the input of a spectrum analyzer. As the system is to be operated under vacuum and at cryogenic temperatures, a suite of microwave switches will be employed to make the connections required to perform this two-tiered calibration. Once the gain from the input of the amplifier to the input of the spectrum analyzer is known, it will be compared to the gain determined using the tunnel junction noise source to determine the unknown loss.

Project Topic: Enabling Baseband and Radio-Frequency Characterization of Supply-Modulated Power Amplifiers Using a Wideband Nonlinear Measurement Platform.

Project Description: This project consists in the extension of the capabilities of an existing nonlinear vector network analyzer (NVNA), in order to provide a measurement platform for supply-modulated microwave power amplifiers (PA). The first objective is to extend the instrument low frequency limit down to baseband (in order to provide measurements on the supply ports). The second objective is to use the instrument intermediate frequency bandwidth of several MHz to provide calibrated measurements both at baseband and radio frequency. Aspects related to large-signal microwave measurements, radio frequency and baseband calibration and behavioral modeling of power amplifiers will be theoretically examined. Most of the work will be devoted to the practical implementation issues of automated measurements. The developed platform will be finally used to characterize a supply modulated PA under realistic excitations.

Project Topic: A Low Noise Amplifier for 5G Applications in 0.13-μm SiGe HBT Technology

Project Description: The proposed project is to design a 28-GHz low noise amplifier (LNA) that is implemented in 0.13-μm SiGe HBT technology provided by IHP, targeting 5G applications. Differential circuitry is selected in order to provide less common mode noise. To our knowledge this work will be the first LNA in differential structure for that frequency. 2dB noise figure and 20 dB gain are aimed to achieve minimum noise and suppress noise of next blocks in the receiver chain effectively. In this project, the gain-noise tradeoff will be the main focus within the consideration of power consumption and linearity. Less than 50 mW power consumption and minimum 5 dBm output 1 dB compression point (OP1dB) are other challenging goals. Full-custom layout will be completed carefully to achieve best match in between post-layout and schematic results.

Project Topic: Development of the technique of terahertz pulse spectroscopy for diagnostic malignant tumors during gastrointestinal surgeries

Project Description: The main goal of the research is developing technique for discrimination oncological and normal tissues by their optical properties and spectral features. Due to the fact that THz radiation is strongly absorbed by water and oncological tissues have increased water content compared with normal tissues it is easy to discriminate these two tissues by intensity of the reflected signals. Additional parameters would be differentiation of optical properties of these tissues.


Konstantinos Katsinos

Project Topic: A Mode Matching Study of Three Dimensional Microwave Structures Using Eigenfunction Expansions.

Project Description: The continuous use of electrically large structures like reverberation chambers for numerous applications, such as electromagnetic interference and immunity as well as MIMO antenna testing, ask for simulation tools for their analysis and design. Using a brute force technique, which requires a tenth of the wavelength discretization, leads to an algebraic system with multi-million unknowns, therefore postulates extreme computational resource. This project aims at the development of a Three Dimensional (3D) Mode Matching Technique for the study of electrically large electromagnetic structures like Reverberation Chambers or Auto-Focused Microwave Cavities. This goal will be established by analytical eigen-function expansion technique able to handle electrically large structures enclosing relatively small objects as antennas, mode stirrers and the device under test which are comprised of complex inhomogeneous media. The idea to be established is based on the field equivalence principle to substitute each inhomogeneity with equivalent electric and magnetic currents on their surface. The fields produced by these equivalent sources will be expressed into eigen-function expansions of the large cavity and determined exploiting their orthogonality.


Muhammad Akram Sobri

Project Topic: Two-Section Flexible Branch-Line Coupler Using PDMS as Substrate and Superstrate.

Project Description: In this project, the flexible two-section Branch-line coupler (BLC) has been designed for operation at 6 GHz. The BLC is a passive microwave component used for power division and has four-port networks. In power division, a power from input port is equally divided between two output ports, providing 90 degree phase difference between these output ports. These features make the BLC useful in various applications such as antenna feeding network, balanced amplifier, and mixer. The BLC is designed and fabricated on Polydimethylsiloxane (PDMS) material as substrate and superstrate using copper foil sheet as a conductive element. The PDMS has several unique properties such as good chemical stability and low dielectric constant. By using PDMS as the substrate, it increases the flexibility of the coupler and makes it easier to be installed on the curve surface of the applications. The dielectric constant for PDMS material range between 2.65 to 2.72. The bandwidth of BLC is limited to 10%-20% due to quarter-wave length requirement. However, with the two-section branch-line coupler, the bandwidth can be increased. The BLC will be simulated, measured and the S-parameters will be analyzed to determine the characteristics of BLC.

Project Topic: Broadband Doherty Power Amplifier Design and Implementation

Project Description: Designing power amplifiers for broadband applications has remained a key challenge for RF engineers in order to minimize energy consumption and hardware redundancy in base station transceivers. The proposed research project aims to design and implement a broadband Doherty power amplifier (DPA). In-depth analysis will be carried out in Advanced Design System (ADS) to recognize the Doherty design space for 10W Cree CGH40010F GaN transistors which will be used in peaking and carrier cells. Output power leakage from carrier amplifier into the peaking path will be minimized by tuning peaking cell bias line.  Conventional DPA output combiner will be investigated and modified to obtain proper load modulation of the carrier cell while considering the knee voltage effect of the transistor to maintain high efficiency at back-off. Potential optimizations in load modulation strategy for wideband applications will be investigated to yield high back-off efficiency. Output combiner employing broadband techniques will be designed to deliver the desired modulation. Separate load and source PCBs will be fabricated and assembled for testing with ADS generated modulated signals.

Project Topic: Effect of signals with a time-varying envelope on RF-energy harvesting and wireless power transfer efficiency.

Project Description:This research focuses on the RF-dc conversion efficiency of rectifier circuits, which plays a central role in developing Energy Harvesting (EH) and Wireless Power Trasfer (WPT) systems which can find widespread practical application. The proposal is to design and fabricate a UHF rectifier prototype and to study its RF-dc efficiency for different time varying envelope signals like multi-sine signals and digitally modulated signals and analyze the effect of different baseband processing parameters on the Complementary Cumulative Distribution Function (CCDF) of the signal envelope and the effect on the obtained RF-dc conversion rectifier efficiency. This thesis has two objectives. First to investigate through simulation and measurements the optimum load which corresponds to the maximum RF-dc conversion efficiency for signals with different time-varying envelope, and how this optimum load varies with the envelope characteristics. Second, to compare the rectifier performance based on the instantaneous power variance (IPV) and peak to average power ratio (PAPR) characteristics of different signals.


Raymond Botty

Project Topic: Very Compact, High Quality LTCC Filter Bank Design

Project Description: Ever-increasing interest in RF and microwave components that meet exacting miniaturization and performance needs for commercial and military applications has pushed the development of cutting-edge design and manufacturing techniques. We will investigate the design of a compact 16-channel switched filter bank operating in the 2-7 GHz range (S-band to X-band). The challenging performance, size, and packaging requirements can be met by realizing the design in low-temperature co-fired ceramic (LTCC) substrate technology. A new double-layered resonator structure allows the resonator length to be reduced to about l/8. Initial design of the individual filters will be based on the circuit model of a combline configuration. After that, a commercial finite element method solver (HFSS) will be used to lay out the 3-D electromagnetic model of the filters, and optimize their electrical performance.


David Garrett

Project Topic: An Antenna Calibration Method for Dielectric Property Estimation

Project Description: Material dielectric properties are of interest for numerous application such as circuit design and biomedical imaging. This project aims to continue developing an improved method of bulk dielectric property estimation using an antenna calibration technique. This permits properties to be assessed with limited manufacturing constraints over a wide range of frequencies, allowing for the cheap and convenient assessment of a variety of materials. Custom ultra-wideband antennas have been developed at the University of Calgary which are designed to be in direct contact with a material under test (MUT) to assess reflected and transmitted microwave signals. Calibration has been previously developed for free-space measurements with antennas separated from the MUT using two simple calibration measurements. This method has been suggested to be adaptable to antennas in direct contact with the MUT and at varying separation distances by modifying the calibration measurements and processing.  Preliminary results from this technique are encouraging, but there are several issues that need to be resolved, namely the property estimation of low conductivity and highly dispersive materials. Advanced simulations as well as controlled measurements will be performed to develop and test this technique.

Medical practitioner and stakeholders such as relatives can view the health information through a password-protected and encrypted web application. The project which applies the concept of Internet of Things (IoT) aims to reinvent the conventional medical practices in the near future via wireless communication electronic circuit design, database management, and user interface application development.


Liam Kelly

Project Topic: Dynamic and Efficient RF Lensing for Wireless Power Transfer over Long Distances

Project Description: Recently, there has been a large increase in the amount of research being conducted in wireless charging techniques. However, the vast majority of those techniques are inductive and require a device to be co-located with the charging station. The goal of this project is to increase the distance at which a device may be located from a station and still be charging. The technique that is proposed to allow for high power transfer rates at distance is radio frequency lensing. Through RF lensing, it is possible to focus power onto a single location in space. Through smart RF lensing techniques, it is proposed to not only transfer power efficiently but also be able to reconfigure a charging station dynamically to track multiple devices and charge them at the same time. To implement the system, a phased array antenna will be used along with a controller. The power will be transferred through an ISM band and control will communicate through a separate ISM band. The final design will be modular to enable greater levels of power focusing with the addition of more transmitter blocks.


Kevin McGrath

Project Topic: Low Data Rate Model Extraction for Digital Predistortion of RF Power Amplifiers

Project Description: The next generation of wireless communications will require signals with far wider modulation bandwidths than are currently in use.  These wider bandwidth signals result in higher data rates. To improve the efficiency of RF power amplifiers (PAs) handling these signals, digital predistortion (DPD) applies digital signal processing techniques at digital baseband to effectively cancel out the distortion induced by the PA.  The output of the PA must be digitized by analog-to-digital converters (ADCs) for comparison to the input signal to extract model coefficients for the digital predistorter. Current ADCs cannot cope adequately with the higher data rates being presented.  There is a need to solve this problem by reducing the data rate of the sampled signal.  This project is focused on designing a new DPD architecture and developing associated algorithms which can carry out the lower data rate model extraction for RF power amplifiers.


Ting Qing

Project Topic: optical vector network analysis based on microwave photonics

Project Description: Several novel approaches to perform an optical vector network analysis (OVNA), using optical double-sideband (ODSB) modulation are proposed. The conventional microwave-photonic-based optical vector analysis is realized using optical single-sideband (OSSB) modulation, which has many limitations. For instance, in the OSSB-based approach, the implementation of the OSSB modulation is critical, which should have a broad electrical bandwidth, high modulation linearity and a large operational wavelength range. In addition, the OSSB-based frequency sweeping can only scan one side, so the measurement range is limited by the bandwidth of the microwave components (usually less than 40 GHz), and the measurement accuracy is restricted by the high-order sidebands. The proposed technique measures the optical spectrum responses by taking use of both the ±1st order sidebands without spectrum response aliasing, thus can double the measurement range eliminate the measurement errors produced by high-order sidebands.


Giulia Maria Rocco

Project Topic: 3-D Printed Reconfigurable Components in Substrate Integrated Waveguide Technology

Project Description: The goal of this work is to develop 3-D printed microwave components based on SIW technology. In particular, the possibility to apply this concept to the design of SIW filters will be studied. A smaller filling factor, indeed, can be adopted to reduce the material density and so to improve the quality factor of the filters. The project will also deal with the development of reconfigurable SIW components. In pursuing this aim, a commercially available liquid metal alloy, called Galinstan, will be adopted. A pipe filled with Galinstan can be used to modify the effective size of the filter cavities, with the aim to shift the pass band. The pipe with Galinstan can also be used to modify the coupling between the cavities. Open points of this work will be the analysis of the material compatibility, in particular to avoid any critical interaction between the Galinstan and the 3-D printed substrate. Moreover, the electrical contact between the Galinstan and the top/bottom ground planes of the SIW structure will need a special care. This project will require a good balance between theoretical and experimental activities, to achieve the implementation and full verification of the prototypes.

Project Topic: Design and Development of a Six Band Energy Harvesting Solution from Ambient Sources

Project Description: The aim of the project is to build an RF energy harvester which covers 6 bands. The basic purpose of covering multiple bands is to increase the total energy harvested so that it is sufficient to drive an appropriate load. One of the aims of the project is to improve RF to DC conversion efficiency by using efficient DC combining techniques which can sum up the energy harvested from each band. The other objectives of the project involve reducing the power losses due to impedance mismatch and analysis of the factors which determine the RF to DC conversion efficiency at various power levels.

Project Topic: Deposition and electrical characterization of nanostructured sensing materials on microstrip resonators. 

Project Description: The development of new topologies of sensors, with increasing low power consumption features, is today of the greatest interest in the market. In such a frame, relatively new category of sensors can be represented by microwave devices with interesting properties in terms of response, low power, wireless compatibility and room temperature operating value. In this project gas sensing properties of  resonant microstrip structures, with circular disk geometry, will be investigated by coating them with sensitive nanostructured layers. The resonators will be realized in a frequency range spanning from 4 GHz to 6 GHz, then  sensing films will be deposited by means of inkjet printer. Accordingly with the geometry ensuring the motion of an electromagnetic wave in the microwave range through the sensing layer, the reflected wave on the material should be affected by the presence of the gas target, namely attenuated and/or out of phase. The gas sensing properties will be evaluated by measuring the reflection coefficient of the devices with a vector network analyzer (VNA).

Project Topic: Novel Analysis and Design of Size-Reduction Microwave Devices with Periodic Structures Using Equivalent Transmission-Line Models and Meta-Smith Charts

Project Description: A quarter-wave transformer (QWT) is a simple and useful circuit component in the design of impedance-matching networks, power dividers and directional couplers. A preliminary study based on using Meta-Smith Charts (MSCs) shows that a properly designed conjugately characteristic-impedance transmission line (CCITL) can potentially offer the QWT property with much smaller electrical size compared to the standard QWT, which is very useful for the significant size reduction of microwave devices. In this project, this interesting CCITL property will be investigated thoroughly using both analytical and graphical (i.e. MSCs) solutions. Once the property of CCITL is completely understood, it would be further applied to design size-reduction impedance matching networks; e.g., multi-section matching transformers. Subsequently, size-reduction power dividers and directional couplers will be considered as well. These size-reduction microwave devices will be implemented and fabricated using periodic transmission-line structures.

Alfiero Leoni

Project Topic: Design and Industrialization of a Tunable Microwave Active Filter.

Project Description: In the last years most RF building blocks have been successfully implemented as IC with different technologies. However, filters working at RF frequency still remain one of the most difficult parts to be integrated, due to the matching requirements, the large area occupation and the dynamic range. In this perspective, filters using Tunable Active Inductors (TAI) have good potential for IC implementation and high-frequency operation; therefore, considerable interest has been shown in the use of active filters. The Faculty Mentor and others from the University of L’Aquila, in the last years, have proposed a new approach for the implementation of active inductors with high linearity and wide dynamic range, but a complete characterization of the proposed TAI solution in practical, industrial applications has not been done and the  potentialities of this solution not yet investigated. In this scenario, the proposed research topic focuses on the design and industrialization of a tunable microwave active filter, responding to real design specifications. An automatic tuning system will be also investigated, since this feature is of real interest for many applications; for instance in the modern, re-configurable, radio systems.

We are using fast switching diodes MEMS (Micro Electro Mechanical Switch), PIN Diodes for switching into different frequencies and by introducing slots in the antennas, thus increasing the bandwidth of antenna. Fast switching into different frequencies can be optimized to achieve the promising solution. Also in this design switching feeds are used by which the design for multiband operations can be implemented.

Beginning with the study on the array factor of a TTD-based beamforming network, the project will investigate microwave photonic filters with high reconfigurability, the structure of the unit, and the usage of the unit in a wideband beamforming system.

James Chen

Project Topic: Design and Implementation of a Tunable Dual-band Microwave Filter

Project Description: Multi-band RF/microwave filters have attracted significant research attention recently due to the growing need for multi-standard multi-frequency wireless communication systems. Conventionally, dual-band filters are designed by parallel integration of two band-pass filters using duplexing elements or cascading a band-stop filter with a band-pass filter to create multiple pass bands. More recently, dual-band filter designs based on dual-resonance resonators have become popular as they allow for easy placement of the two passbands. The proposed research topic focuses on the design and implementation of a tunable dual-band cavity filter by building upon previous research works on dual capacitively loaded cavity resonators and tunable evanescent-mode cavity with lumped tuning elements. Several design parameters will be investigated, such as the optimal resonator design for the highest Qu while maintaining a wide tuning range and the optimal coupling structures for independent bandwidth control.

Kristian Dimitrov

Project Topic: Design and implementation of fractal antenna for RFID applications.

Project Description: This research if focused on design of a RFID antenna by implementing fractal structures in the antenna’s topology. The advantages of using fractal antenna for RFID applications is achieving minimum size of the antenna and multiple bands frequency properties. As the signals used are less than 5MHz in bandwidth at 870MHz which corresponds to 0.57% relative antenna bandwidth, the provided frequency band of such antenna is sufficient for that purpose. By implementing deterministic fractals, such as Cantor set, Koch snowflake, Julia set and Sierpinski gasket; the available space can be filled most effectively, leading to topology that is electrically long, but occupying less space. Also characteristics like efficiency and gain will be optimized.

In the following research, several novel structures will be proposed and analyzed in theory. Then, microwave simulation software is utilized to obtain the best performance. After that, they are fabricated to validate my ideas. Finally, the design methods are summarized and several relative papers will be submitted.

Project Topic: Development of an automated system to obtain dielectric property measurements of materials using an open-ended coaxial probe

Project Description: This project seeks to automate a test system for use in a biomedical imaging lab. The system is used extensively by the Tissue Scanning Adaptive Radar (TSAR) group at the University of Calgary to characterize materials by measuring their dielectric properties. The system uses an open-ended coaxial probe connected to a Vector Network Analyzer (VNA) to measure the reflection coefficient between the surface of the probe and the material of interest. The collected reflection coefficient data is stored and processed to obtain the dielectric constant and conductivity of the material of interest over the frequency range of the measurements. The project will automate the setup and calibration of the test system, along with the measurement procedure and data processing. The automated system will then be tested and validated by comparing the results of its measurements with previous manually obtained values. An intuitive, easy to use user interface will also be developed to tie all aspects of the system together.

Chenhui Liu

Project Topic: Non-contact Hand Interaction with Smart Phones Using the Wireless Power Transfer Features

Project abstract: Wireless charging is now a very competitive feature for smart phones. Instead of using the Wireless Power Transfer (WPT) coil to receive inductive power, an oscillator is built using the WPT coil as part of the resonant tank. Whenever human hand interact with the electromagnetic field sent out by the coil, it will result in the impedance change of the coil which will finally change the resonant frequency of the oscillator. The interaction between hand and coil then can be monitored by the frequency change, thus enabling the non-contact interaction between human and smart phone.

Project Topic: Design of a 2.45 GHz FMCW Radar Altimeter for CanSat.

Project Description: The project consists in the design of a embedded FMCW radar altimeter for CanSat. A CanSat is a system reproducing the behavior of a spacecraft, whose volume and weight are strongly constrained. The radar design consists in a bistatic system, with one antenna used for the transmission, and another used for the reception.

The processing of the received signal allows determining the altitude and the speed relatively to the ground via the measurement of the travelling time and the Doppler frequency shifting. The main goal is to design an efficient radar system sufficiently integrated. The deadline for the project is August 2015.

Project Topic: A Low Phase Noise X-Band Microstrip VCO with Wideband Tuning Range

Project Description: The work is entirely focused on the design and implementation of an X-Band microstrip Voltage-Controlled Oscillator (VCO) based on a HJ-FET with more than %20 tuning bandwidth. It is also desired that its free running frequency is about 10 GHz. Desired output power of the oscillator is more than 0 dBm. Additionally, size of the circuit is smaller than 1 inch2.  The design of the low phase noise planar microstrip VCO with wideband tuning range is already very challenging topic. In this project, the trade-off between the tuning range and phase noise performance is investigated carefully. A planar resonator structure is considered to provide acceptable phase noise performance on wideband tuning range.

Numerous models of humans will be developed with specific target that those models can be used within electromagnetic field simulators. A large number of crowd models with stochastic distribution of humans will be created and simulated, in order to obtain statistics of electromagnetic field propagation within these crowds. For the simulations, a 3-D electromagnetic solver based on surface integral-equation formulation, higher-order basis functions and Galerkin testing will be used, utilizing graphical processing units. A series of semi-anechoic chamber measurements will be conducted in order to correlate measurements with the simulation results. Finally, a number of crowd models will be simulated in order to investigate the effect of crowds on wave propagation in ad-hoc wireless networks.

Project Topic: Transition Design for Active SIW Components

Project Description: The proposed project is a multi-function transition design for active substrate integrated waveguide (SIW) components. With the current semiconductor technology, transistor and diode are mounted on microstrip circuit, to reach the goal of DC basing, impedance matching and fundamental requirements. Besides, various SIW passive circuits with performance enhancement are proposed. The two concepts are integrated into a single platform. Unlike the conventional SIW-to-microstrip line design, the proposed transition achieves the functions of DC de-coupled, low loss, wideband, compact, impedance transformation and mode matching. Introducing two proposed designs is aimed, with series stub concept and inserted microstrip line concept respectively, as a leading system-on-substrate technology for the implementation of cost-effective and high performance millimeter-wave and terahertz circuits and systems.

Yuting Wei

Project Topic: Digital Cancellation of Nonlinear Self-Interference in Full-Duplex Wireless Transceivers

Project Description: In-band full-duplex technology enables wireless transceivers transmit and receive signal at the same frequency simultaneously. If successfully implemented, it could potentially cut the spectrum needs by half in wireless communications. The main challenge of such systems lies in effective cancellation of the self-interference that caused by the transmit signal added to the received signal. Intensive research has been conducted in this field but the majority of the work assumes the transceiver chain is linear. In practice, however, nonlinear distortion induced by the non-ideality of transceiver components can form a bottleneck in full-duplex systems. Furthermore, present research often applies a simple channel model to simulate the channel between transmitter (Tx) and receiver (Rx), which is unable to accurately represent the characteristics of the real channel in full-duplex mode. In this project we will focus on modeling of self-interference induced by nonlinear components and non-ideal channel in the transceiver chain and we then develop effective cancellation algorithms in digital domain to eliminate such nonlinear effects.

Project Topic: Self-interference cancellation circuits for single-channel full-duplex wireless communication

Project Description: In current state-of-the-art wireless communication technology, the operation of the transmitter and the receiver in a wireless node is separated in either time (TDD) or frequency (FDD) domains. Given this, a fundamental question arises – can we transmit and receive concurrently at the same frequency? This paradigm, quoted in literature as ‘single-channel full-duplex wireless communication’ has gained much attention recently due to theoretical doubling of available bandwidth. The key issue in the development of such systems is the large interference from the transmitter into the receiver in the wireless node. Conventional RF filtering cannot be used as both the desired signal and the interference occupy the same frequency band. This research proposal aims at the implementation of an RF self-interference cancellation circuit for such a system that will also need to be adaptive due to uncontrolled factors such reflections of radio signals from multiple surfaces. The proposed integrated circuit will be fabricated in an RFCMOS process and experimentally validated.

Impact statement: "It has been an honor and highly motivating experience to receive the MTT-S pre-graduate award. The award has given me a feeling of accomplishment, and an urge to contribute back to the microwave and RF community. Attending IMS 2015 was a great learning experience on its own. I had the opportunity to meet the stalwarts of the community and discuss my work with a few of them, which gave me new ideas and insights. As my immediate career plan, I wish to pursue a doctoral degree in the field of RFIC design."

Project Topic: Design and implementation of a wideband beamforming network for LTE and W-CDMA applications featuring a compact 16x16 Butler Matrix

Project Description: In present day wireless communication systems, due to the exponential increase of users, there is a need for greater uplink and downlink speed capacities. For that reason, base stations antennas are being designed to increase the coverage area, speed capacity and provide special diversity while reducing interference. In this research project, a beam forming system will be designed featuring a compact wideband 16x16 Butler Matrix composed of compact branch-line couplers and Schiffman phase shifters and without the use of crossovers for further size reduction. Also, a 16 element high-gain antenna array with low cross polarization will be introduced to function as the phased array. The beamforming system will operate between 1.7 GHz and 2.2 GHz so as to cover the AWS and PCS 1900MHz bands which are used in Peru to deploy 4G and 3G mobile communication networks.

Impact statement: "The MTT-S Scholarship I was awarded has been a great start and an outstanding experience and motivation for my professional career as a Telecommunications Engineer.

Project Topic: SDR Based Wide-Band Frequency Transceiver for UWB Medical Imaging.

Project Description: The proposed project is to design and develop a wideband RF transceiver for 3-12 GHz which is intended for UWB medical imaging. Abnormalities in the human body have a noticeable dielectric contrast when compared with normal biological tissue. An UWB transceiver will send and receive signals over a wide band of frequencies. By directing the signal at biological tissue, it is possible to analyse the reflected signals from the tissue to determine its electrical properties (i.e. dielectric) and therefore, detect and classify abnormalities in biological tissue. The wide-band transceiver will interface with a computer using a software-defined radio operating in the lower frequency bands and will up and down-convert the output and input respectively to create a wide-band transceiver system. Using the developed hardware, algorithms can be developed to utilise this wideband transceiver system for UWB medical imaging.

Impact statement: "I am very grateful to receive a MTT-S scholarship as this award has aided me throughout my thesis and has encouraged me to pursue higher levels of education. In this program, I was given the opportunity to attend IMS 2015 which had exposed me to industries and to emerging areas of microwave engineering. Attending IMS 2015 was a great experience and I will treasure it as I plan for the future and seek to build a career in microwave engineering."

Project Topic: Dual-Band Antenna Based on Molded Interconnect Device Technology for Experimental Rocket Telemetry Application

Project Description: The proposed research topic consists in the design and fabrication of a dual-band antenna based on Molded Interconnect Device (MID) technology. The MID technology allows to includea conductor within a 3-dimentional (3-D) molded object in order to obtain low weight and non-protuberant antennas. To demonstrate the advantages of the MID technology, for airspace applications, a dual-band antenna will be implemented within the molded nose cone of an experimental rocket. The global project consist of designing, fabricating and testing the dual-band MID antenna, a 2.45 GHz on board transmitter to transmit telemetric data during the flight and a 2.45 GHz ground base receiver both based on COTS (Commercial off-the-shelf). For redundancy purposes, an ISM 868.5 MHz frequency link is also used. The EirSpace student association will design the experimental rocket on which the project will be implemented. The rocket will be launched during the C’Space event of August 2015 organized by the French government space agency: CNES (Centre National d’EtudesSpatiales).  

Impact statement: "Receiving the MTT-S scholarship was a great motivator for me, proving that my project was recognized by the scientific community.

Project Topic: Compact Antennas With Low Cost Integrated Feed Systems For Space Communications And Arctic Surveillance

Project Description: Compact satellites, or microsatellites, are transforming space-based surveillance systems. Typical configurations include a network of small satellites that can offer increased coverage and enhanced data collection rates when compared to conventional large scale systems. Microsatellites can also drastically reduce launching costs and mission development time, thus making remote sensing technologies more cost effective. Applications include vehicle tracking, Arctic surveillance, crop growth analysis, and climate change observation. The objective of the proposed research project is to research, design and test some new and compact antennas with integrated feed systems for such microsatellites while also making comparisons to more common designs in terms of size, cost, and performance.

Impact statement: "The MTT-S undergraduate research scholarship has encouraged and supported me in entering the field of antenna design as well as their integration with feeding networks, optimization approaches, and isolation techniques for improved device efficiency. Support in attending an MTT-S conference will allow me to broaden my knowledge in the field and make connections in the industry."

Thomas Roth (Report)

Project Topic: Design of Active Frequency Selective Surfaces for Wideband Operation

Project Description: Frequency selective surfaces (FSS) are formed by a periodic array of conductors on a substrate. The various forms of coupling between conductors create a resonant response when excited by electromagnetic radiation. A new development for these structures has been to add an active element, creating an active frequency selective surface (AFSS).  This allows the response of the entire structure to be electrically tuned, opening many new possibilities for uses.  Currently, an AFSS is designed by first developing a FSS with the desired frequency response.  An active element is then added to the unit cell, often resulting in low tunability.  The focus of this project is to approach the design of an AFSS with the goal of increasing the range of tunability to cover a wider band of operation.  This requires a new focus in designing the unit cell so that it can be maximally affected by the active element, while still generating the desired frequency response.

Impact statement: "This scholarship was influential in allowing me to pursue my own research topic, as well as fabricate a structure to test the concept.  My attendance to IMS through this scholarship and the research experience helped me to decide that I would like to pursue a graduate degree and have a career focused in research related to electromagnetics."

Project Topic: Microwave Noise Characterization of GaN HEMT’s under Pulsed Illumination

Project Description: The aim of this project is to evaluate the effect of pulsed illumination on the noise behavior of GaN HEMT’s. Starting from the previous research on GaAs devices under CW red laser illumination, the measurement system will be modified, especially the optical section, to enhance the effects on HEMT’s. Furthermore, the microwave low-noise receiver will be improved to obtain the best sensitivity in noise parameter determination. The difference on the device noise performance between CW and pulsed illumination conditions will be investigated.

Impact statement: "The MTT-S Scholarship program gave to me a significant opportunity and one more reason to study and to spend my time in the microwave field. I am very grateful to the society for the award, an important recognition in my career. I am working in the microwave electronics laboratory of the university of Messina and I deal with the characterization of advanced devices, at the same time. I would like to continue working in this fascinating field, especially with measurements system and instrumentation. "

Project Topic: Harmonic Phase Reference for Measurement of Modulated Signals with a Nonlinear Vector Network Analyzer.

Project Description: One of the state-of-the-art measurement instruments allowing engineers to characterize non-linear behavior of a device or a system is a non-linear vector network analyzer (NVNA). This instrument allows for a very wideband measurement (from a few MHz to 67 GHz) of amplitude and phase spectrum of voltages and currents at circuit’s terminals. From these spectra the time domain voltage and current waveforms can then be built. The NVNA needs to be calibrated before the measurement. One of the crucial steps of this calibration is a phase calibration. In this calibration, a device with a known phase spectrum is measured, which allows to correctly reconstruct the phase relationships between different frequency components measured by the NVNA. Typically, a comb generator is used as a phase reference element (HPR). However, when performing measurement of real-life modulated signals, the repetition rate of the HPR pulses has to be kept very low, thus, the signal-to-noise ratio of each frequency component becomes very small, which significantly deteriorates the measurement accuracy. The solution is to drive the HPR with an appropriately chosen pulse train. The key is to optimize the pulse train so that the maximum energy is concentrated at the particular frequency and its harmonics with a desired frequency spacing. The topic of this proposal is to build and test a hardware implementation of an HPR driven with optimized pulse trains. The new HPR is expected to improve the measurement accuracy of non-linear microwave circuits operating with modulated signals.

Impact statement: "The fact of being an IEEE MTT-S Undergraduate Scholarship awardee is a motivating impulse for a young engineer like me. It gave me a feeling of being appreciated and emphasized the importance of my work, and it influenced me to research deeper into microwaves. The project of harmonic phase reference (HPR) has been successfully developed thanks to the help I received from MTT-S. "

Project Topic: Portable FMCW Radar Sensor with Smartphone Interface for Indoor Positioning and Motion Analysis

Project Description: This project describes a hybrid portable FMCW radar sensor operating at 5.8GHz aims at indoor positioning. Unlike conventional Doppler radar and FMCW radar, this radar works in two modes, i.e., FMCW mode and CW interferometry mode, thus it can detect Doppler shift and absolute distance at the same time. To increase the precision of the system, a new signal processing method will be adopted, which can extract useful information from the output signal. In addition, Bluetooth is used for data transmission and moreover, a new smartphone interface is proposed to develop in Labview for Android system through Bluetooth.

Impact statement: "I would like to thank the MTT-S undergraduate scholarship program for supporting this project and my attendance to the academic conference. This amazing scholarship program helped me to better understand important concepts in microwave systems, besides exposing me to the state of the art in this field. On the other hand, this program spurred my decision to a PhD degree on the same topic. I will continue my study on this project in the future. Many thanks once again to MTT-S for this undergraduate scholarship."

Project Topic: Miniature Microwave Sensors for Agricultural and Environmental Applications.

Project Description: There are two types of sensors that will be investigated. The first group consists of sensors of physical parameters which can be measured by directly measuring some electrical variable which is dependent on the sensed parameter. This research will aim at designing miniature soil independent soil moisture sensor for applications in wireless sensor networks. The second group of sensors is the sensors of physical parameters which cannot be measured by directly measuring some electrical variable, due to the fact that the electrical properties of the sensor are not influenced by the physical parameter in question, e.g. NOX (nitrogen-oxide) sensors. The applicant will investigate the use of nano-membranes designed to be sensitive to nitrogen and its oxides, and then investigate the possibility of incorporating such nano-membranes in microwave sensors designed using low-temperature co-fired ceramic (LTCC) technology and/or flexible and organic printed electronics. 

Impact statement: "Being awarded the IEEE MTT-S Undergraduate Scholarship is a great honor and a much appreciated recognition of my work and academic efforts.

Project Topic: Wireless Sensors in Paper-Based SIW

Project Description: The continuous demand for high-performance and low-cost devices in the microwave application field pushes the research into the seek for new materials and new technologies to replace the older and outdated ones. This project aims at designing, manufacturing and measuring wireless sensors in cavity-backed slot antennas which benefit from the advantages of paper, a well-known, extremely cheap and eco-friendly dielectric to be used as substrate. Furthermore, SIW technology will be exploited to implement the sensors in order to feature very small size, high accuracy, manufacture simplicity and economical fabrication process. Despite the numerous advantages, some technological issues need to be sorted out. Firstly, paper’s high losses have to be reduced and secondly energy-harvesting systems have to be integrated with the sensors. This project will carefully explore such side-problems and try to devise effective solutions to them.

Impact statement: "The MTT-S Scholarship has impacted positively on the choices for my future career, promoting my interest in the microwave applications. It has given me the great opportunity to attend the IMS 2014, an inspiring experience which has enabled me to network with many teachers, managers, and students from all over world, in an explosion of ideas and passion.

Project Topic: Compact Photonic Processors for Processing Microwave Signals Based on a Dual-drive Mach-Zehnder Modulator

Project Description: In this project, the microwave photonic signal processing based on a dual-drive Mach-Zehnder modulator (DMZM) will be implemented. DMZM is a highly integrated and commercially available electro-optical device for optical fiber communications. The potential of DMZM for microwave photonic applications, however, has not been sufficiently developed. Based on the DMZM, a microwave photonic signal processor with simpler, more compact and stable configurations can be realized. This project will investigate wideband optical single sideband (OSSB) modulation, photonic phase-coded signal generation, photonic microwave mixing and optical beam forming.

Impact statement: "I would like to thank MTT-S society for providing me this undergraduate/pre-graduate scholarship, which is really important for my career.

Lei Zhang (Report)

Project Topic: Thermal Power Reuse in Power Amplifier Design

Project Description: In this project, an alternative efficiency enhancement for power amplifier (PA) with thermal power reuse was proposed. Unlike the conventional efficiency enhancement techniques such as switching-mode, Doherty, or Chireix PAs, thermal power generated by the transistor itself is converted by a thermoelectric generator into DC power. It provides electronic insulation between the transistor and the heat sink. More importantly, it provides a "non-circuit" approach that could be further combined with "circuit" approaches to achieve a high efficiency power amplifier for various applications. 

Impact statement: "I was still undecided whether to continue my postgraduate study. I enjoy doing research and analysis but I was just not sure if I had the capabilities to do so. MTT-S scholarship has influenced me and changed my thoughts. It gave me positive feedback and encouragement in my research. It also motivated me to continue my career in the research field and helped highlighted my work by allowing its publication in the MTT-S website. Upon graduation from City University of Hong Kong, I am now pursuing M.Eng degree in Cornell University in the U.S."

Project Topic: Baseband Signal FPGA Programming for Application in Amplifier Linearization Technique that uses Second Harmonic

Project Description: According to the current trends, intention is to modify the linearization technique toward a digital processing of baseband signal that will be further exploited to modulate the fundamental carrier second harmonic. The aim of this project is to create required In-phase and Quadrature- phase baseband signals for linearization, which will modulate carrier at the second harmonic. The process will be performed by programming appropriate FPGA board. The modulated signal at the second harmonic is then injected at the input of the amplifier transistor together with the fundamental signal and also fed at the transistor output in order to reduce the intermodulation products. The modulated second harmonic and the fundamental signal are mixed due to the second order nonlinearity of the transistor that generates additional third-order nonlinear products that may suppress the original intermodulation products distorted by the transistor nonlinear characteristic.

Impact statement: "Receiving a MTT-S scholarship has greatly encouraged me in moving forward in achieving my objective to deepen my knowledge. While I was working on this project, I gained lots of new knowledge in the field of hardware implementation. Attending EuMW 2014 allowed me to network with colleagues from all around the world, provided me with a wider perspective on the progress of technology development and the latest technical resources. Most importantly, by attending EuMW 2014, I was presented with an unexpected opportunity to pursue my PhD in Ecole Politechnique, Montreal, Canada, since I met my current PhD supervisor, Prof. Ke Wu."

Project topic: Cryogenic MEMS Reliability Testing

Project Description: The project is part of a large research effort aimed at designing and building an apparatus to measure small differences in the cosmic microwave background radiation.  Due to the sensitive nature of the apparatus, the switches in the system must have a fast rate while having low power consumption.  The project will be realized in the lab working with has designed switches based on MEMS (microelectromechanical switches) technology.  The project will be to verify the reliability of these switches, which is very important as they will be used in a satellite and cannot be easily repaired.  This will be done by fabricating a testing chip with many switches in parallel and then using LabView (a computer program) to switch the MEMS very rapidly over millions of cycles, and then record when the switches break down.  The switching will take place in a cryogenic chamber to simulate conditions in outer space.  This data will then be analyzed to determine the breakdown characteristic of the MEMS switches.
