Design of Scalable and Low Complexity Phased Arrays
Date of original webcast: Tuesday, July 9, 2019
Recent requirements in 5G communication and advanced driver assistant systems have drawn an increasing interest in utilizing phased array technologies. Bandwidth intensive applications such as real-time video streaming and emerging gigabit wireless communications demand higher data rates than ever before. The spatial selectivity of phased arrays can increase the channel capacity and data rate without requiring extra bandwidth. Furthermore, the spatial filtering nature of the phased array systems alleviate the problem of multipath fading and co-channel interference by suppressing signals emanating from undesirable directions. Unfortunately the high cost of phased arrays has been the primary impediment to their deployment in many commercial applications. Several new approaches for the design of new phase shifters and phased arrays will be presented to reduce the size, cost and complexity of the conventional phased arrays.
