In-situ active impedance characterization of scanned array antennas
Abstract
Various embodiments presented herein relate to determining mutual coupling between a pair of antennas in an array antenna. Various operations presented herein enable comparison between a magnitude and phase of a signal transmitted from a first feed network (via a first antenna) and a magnitude and phase of a portion of the signal received at a second feed network (via a second antenna). Electrical effects engendered by any of the first feed network, a first switch, a first local circuit, the second feed network, a second switch, and a second local circuit can also be determined and their effects mathematically removed. Based upon the foregoing, a mutual coupling between the pair of antenna is determined.
