Multifunctional Antennas and Arrays for Wireless Communication Systems
This chapter presents phased array antenna discussion by employing emerging 5G silicon RFICs. Phased array antennas are a subset of reconfigurable antennas in that the pattern can be reconfigured and scanned. Significant progress has been made in thi
