Abstract
A feed structure (24) is disclosed which facilitates reception of orthogonal linearly polarized signals from communication satellites. The structure includes probes (34, 36) combined in a cavity (28) with transmission members (50, 52) and an isolation member (54). The structure is particularly suited to enhance high signal to noise ratios because of short path lengths to external receiver circuits and to enable realization in simple economical one piece castings. The teachings of the invention are shown extended to dual band feed structures (124).
