Professor Ghalichechian presented at the Radio Club of America!

Professor Ghalichechian presented at the Radio Club of America Technical Symposium, held at Hyatt Regency Hotel in downtown Atlanta, November 19, 2022. His talk was titled: “Antennas and Arrays for Future 5G Systems”

Abstract: Today’s wireless communications systems operate mostly in the microwave bands, which have become a crowded and limited resource. Yet significantly larger bandwidth is available in the mmWave band of 30 to 300 GHz, offering the potential of huge increases in data rates for next generation devices. This talk will review the state-of-the-art in antenna and array research for future mmWave systems. Furthermore, recent research and progress made at Prof. Ghalichechian’s mmWave Antennas and Arrays Laboratory at Georgia Tech is presented.
