Abstract
An antenna 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. The antenna includes two coplanar concentric patches. The inner patch is substantially square. The outer patch surrounds the inner patch to define a gap therebetween. A resonant parallel inductive/LC circuit interconnects the two patches. The circuit includes a plurality of printed traces within the gap and interconnecting the concentric patches. The gap and each trace function as an LC circuit.
