Due to the increased demand for data, there is a need for base-station and mobile-user phased-arrays which can provide high-capacity communication links using directional antennas, both for terrestrial and satellite (SATCOM) applications. Therefore, there is a large investment by industry to meet the commercial demand. Digital-beamforming phased-arrays at the element level for sub-6 GHz systems, and hybrid (i.e. analog/digital) beamforming for the SATCOM Ku and Ka-band and mm-waves 5G bands have being recently developed using low-cost CMOS and SiGe silicon technologies. High EIRP, low NF high-performance phased-arrays at 10-14 GHz (Ku- band SATCOM), 17-21 GHz and 27-31 GHz (Ka-band SATCOM), 24-29.5 GHz (5G), 37-42 GHz (5G) and even 57-64 GHz (WLAN), and with multiple beams, are now available. These arrays are also used in low-cost radars for landing systems, weather detection and UaV collision avoidance. This talk introduces different topologies and solutions for microwave and mm-wave phased-arrays, summarizes our work in this area, and presents a roadmap for the future.

Biography:

Prof. Gabriel M. Rebeiz is Member of the National Academy (elected for his work on phased-arrays), and is a Distinguished Professor and the Wireless Communications Industry Endowed Chair at the University of California, San Diego. He is an IEEE Fellow, and is the recipient of the IEEE Daniel E. Nobel Medal, the IEEE MTT Microwave Prize (2000, 2014, 2020), the IEEE MTT Distinguished Educator Award, the IEEE Antennas and Propagation John D. Kraus Antenna Award, and the IEEE AP-S Wheeler Paper Prize. His group has led the development of complex RFICs for phased-array applications from X-band to W-band, culminating recently in wafer-scale integration with high-efficiency on-chip antennas. His is considered to be the father of affordable phased-arrays, and his 2x2 and 4x4 RF-beamforming architectures, single- and multiple-beams, are now used by Renesas, ADI, NXP, P-Semi/Murata, Infineon, Sivers, Ampleon, Nokia, Qualcomm, Intel, Samsung, Boeing, Raytheon and others, and most companies developing communication and radar systems. Also, all SATCOM affordable phased-array development is based on his work and architectures. His group has published more than 850 IEEE papers, and he has graduated 102 PhD students and post-doctoral fellows.
