Abstract
Methods and Systems for testing phased antenna arrays include positioning a phased antenna array and a probe antenna at relative positions with respect to each other where one of them can operate as the transmitter and the other as the receiver. The transmitter can radiate a plurality of electromagnetic waves sequentially while the phased antenna array is steered or configured differently for each radiated electromagnetic. The receiver can receive, responsive to each radiated electromagnetic wave, a corresponding receive radio frequency (RF) signal. A processor can determine one or more performance parameters of the phased antenna array using the receive RF signals.
