Abstract
A full aperture interleaved space duplexed beamshaped microstrip antenna system wherein the separate transmit and receive microstrip antennas each has respective arrays of radiating patch elements. Each of the antennas is fed from a single end thereof so that each antenna creates four beams. Beam pitch angles are introduced into each antenna so as to reduce the coupling between adjacent lines to allow the gap within each connected line pair to be reduced. This gap reduction provides room for the antennas to be interleaved within a common rectangular aperture so that the separate feeds are at opposite ends of the aperture. Each antenna then utilizes the entire aperture. Isolation elements are provided between the lines of the transmit and receive antennas so as to reduce the mutual coupling therebetween and maintain the minimum required sixty dB isolation.
