| 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. |
