Abstract
Systems and methods for partitioned phased array fed (PAFR) antennas with improved throughput capacity are disclosed. The phased array in a PPAFR antenna is partitioned into multiple partitions of antenna elements that can be operated by corresponding beam forming networks with reduce sized, weight, and power consumption characteristics to independently and simultaneously to generate angularly offset static and dynamic spot beams patterns. The independently generated spot beam patterns can be configured to include transmission and receiving spot beams for establishing a number of pathways. Accordingly, the number of pathways a particular partitioned PAFR antenna system can support relative to an unpartitioned PAFR antenna system can be increased while also using smaller and lighter configurations of beam forming networks.
