Biography

Alessandra Costanzo (M’99-SM’13) received her laurea-degree in Electronic Engineering (summa cum laude) from the University of Bologna, Italy, in 1987. In 1989, she joined the University of Bologna as a research associate where she became associate professor in 2001. Since 1995 she has been teaching courses in Electromagnetic Field Theory, Microwaves, Nonlinear microwave Circuit Design, Numerical Techniques for Electromagnetics and Bioelectromagnetics. She has been a Supervisor of many M.S. and B.S. students and a Tutor of several Ph.D. students.

Her research interests focus on the design of RF/microwave circuits and systems, including multiple input multiple output (MIMO), ultra-wide- band (UWB), RF identification (RFID) and highly innovative multi-band rectennas, specialized for wearable applications. She is now involved in multiple research activities related to wireless power transmission technologies, adopting both far- and near-field solutions. She has developed innovative sensing solutions, based on EM interference for non-invasive structural monitoring.

She authored more than 150 scientific publications in peer-reviewed international journals and conferences, and several book chapters. She holds three international patents.

Alessandra Costanzo is Senior Member of the IEEE since 2013. She is currently the chair of the IEEE Microwave Theory and Techniques Society (IEEE MTT-S) MTT-26 (Wireless Energy Transfer and Conversion) where she served as vice-chair in 2014-2015. She is AdCom member of the Council of RFID (CRFID) as MTT-S representative. She is member of the IEEE MTT-24 (RFID). She is a co-founder of the EU COST action IC1301 WiPE “Wireless power transfer for sustainable electronics” where she chairs WG1: “Far-field wireless power transfer.” She was the chair of the workshops and focus sessions for the EuMC2014, where she also the organizer of the IEEE Women in Microwaves event (WIM). She regularly serves as reviewer for many IEEE Transactions and Journals, such as the Transaction on Antennas and Propagation, on Power Electronics in Industrial Electronics, Circuits and Systems, beside the Transaction of Microwave Theory and Techniques. She is executive editor of the Cambridge Journal of Wireless Power Transmission and of the International Journal of Microwave and Wireless Technologies. She is member of several technical program committees including the IEEE MTT-S International Microwave Symposium (IMS), the European Microwave Conference (EuMC), the IEEE Wireless Power Transmission Conference (WPTC), the IEEE International Conference of UWB and the IEEE RFID-TA.

High-Accuracy Passive UWB Localization by Optimized Energy Sources

This lecture overviews the available techniques for localizing battery-less devices with high accuracy Then it proposes a novel design approach of an entire RF/microwave energy harvesting link based on the concurrent optimization of the (low) power sources and of the remote of batteryless device, to enable high-accuracy localization. This is obtained by harvesting the higher-order harmonics, generated by the rectifier non-linearity excited by optimized multi-sine excitation signals whose tones are optimized at the circuit level with respect to number, spacing and amplitude distribution. Real-time signal processing techniques can locate such a tag with centimetre level accuracy.

The tag technology is very simple and  can be exploited in several energy-aware applications for  massive environmental monitoring, adopting  eco-compatible  materials.
