Over-the-air assessment of FR2 active antenna array using a compact range benchtop antenna system

This paper study the performance of a compact measurement solution to calibrate and assess over-the-air (OTA) performance of FR2 active antenna array. Radiation pattern can automatically measured for multiple beamforming configurations in Tx and Rx mode. The open configuration make the debug and testing easier in the early stage of the project. A 4*2 beamforming array at 26GHz is measured in order to assess the performance of the amplitude and phase control.
