Abstract

A pair of spaced apart resonant microstrip radiators is fed from two differently polarized input/output ports by respective different feedlines to achieve different respective polarizations while at the same time minimizing undesirable r.f. coupling between the input/output ports. The preferred design embodiment minimizes feedline length while simultaneously increasing the r.f. isolation between the two differently polarized input/output ports.
