Abstract
A space duplexed beamshaped microstrip antenna system including transmit and receive antennas, each of which has two groups of interleaved arrays. The array groups are slanted in opposite directions and each is fed from opposite corners of the antenna so that each group utilizes its entire assigned reduced width aperture to create the required beam contours for two beams. To achieve frequency and temperature compensation, one of the antennas is made up of forward firing arrays and the other of the antennas is made up of backward firing arrays.
