Advanced Satcom Satellites require uplink (30 GHz) and downlink (20 GHz) antennas providing regional earth coverage (Canada, CONUS, Alaska, Hawaii and Puerto Rico) using high gain multiple overlapping spot beams. The antenna coverage with 128 beams that are arranged in a hexagonal grid fashion is shown in Figure 1. Critical antenna design parameters… CONTINUE READING
