ABSTRACT:
Various embodiments provide antennas capable of receiving both left-hand circularly polarized (LHCP) signals and right-hand circularly polarized (RHCP) signals, and outputting both signals on a single feed. In one exemplary embodiment, an antenna generally includes two substantially coplanar concentric patches. The inner patch is substantially square. The outer patch has inner and outer edges both of which are substantially square. The two patches do not physically contact one another. A single feed is connected to the inner patch. The inner patch receives the LHCP signal, and the two patches operate collectively together for receiving the RHCP signal.
