Affordable Phased-Arrays and Reflect Arrays (RIS) for SATCOM, Radars and Terrestrial Communications (5G/6G) Using Silicon Beamformer ICs

Affordable phased-arrays, built using low-cost silicon chips, have become essential technology for high data-rate terrestrial (5G) systems to their high gain, electronically steerable patterns, narrow beamwidths, high tolerance to interference and adaptive nulling capabilities. High performance phased-array communication systems at X-band to Ka-band and D-band (140 GHz) with single and multiple beams will be presented, together with radar and sensing arrays. We will also present our recent work on reflect-arrays at 3-6 GHz, 14 GHz and 28 GHz. Also, work done using meta-antennas with sub-wavelength spacing will be presented as an alternative approach to silicon-based systems. Finally, methods to reduce the power and to build multiple frequency systems will be presented and with excellent performance.

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 MTT Microwave Prize (2000, 2014, 2020) all for phased-arrays. His 2x2 and 4x4 RF-beamforming architectures are now used by Renesas, ADI, NXP, Infineon, Sivers, Qualcomm, Intel, Samsung, Boeing and others, and most companies developing communication and radar systems. All SATCOM affordable phased-arrays are based on his work and architectures. He has published 900 IEEE papers with an H-index of 104 and has graduated 125 PhD students including the former CEO of Qualcomm and several VPs in the communications and defense industry. He is a cofounder of Extreme Waves Inc., San Diego, CA, a company of 30 RF engineers doing advanced SATCOM systems, communication systems and phased-arrays.
