Ka-band dual frequency array feed for a low cost ACTS ground terminalBecause of low cost and ease of fabrication, microstrip arrays are attractive as feeds for reflector antenna systems. The development of a 4 x 4 microstrip array which will be used as a feed for a low cost Advanced Communications Technology Satellite (ACTS) ground terminal is described. The array feed consisting of four 2 x 2 subarrays is fed with coplanar waveguide power dividing networks. The patch radiator is designed to excite two orthogonal, linearly polarized waves at Ka-band frequencies (around 20 and 30 GHz). Test results for the developed array are presented.
