V-Band Beam-Switching Transmitarray Antenna for 5G MIMO Channel Sounding

Abstract : Beam steering antennas are attractive solutions for beamforming channel sounding applications and multi-beam massive multiple-input multiple-output (M-MIMO) systems. The antenna proposed here consists of a transmitarray antenna fed by a patch antenna array operating in V-band (57 - 66 GHz). The transmitarray is made in PCB technology with 8-phase state unit-cells. The focal array is a four-patch array excited by a standard microstrip corporate feed network. The simulation results demonstrate a wide scan range (72 degrees) with a peak gain of 22.9 dBi at broadside and with scan loss of about 4.2 dB in E-plane and H-plane for the most offset beams.
