ABSTRACT:
Described is an apparatus and method for reducing noise in an information bearing signal is provided. A feeding element receives dual-polarized wideband electromagnetic signals. The feeding element is coupled to a Non-Cutoff Frequency Selective Surface ground plane. The Non-Cutoff Frequency Selective Surface ground plane allows for a line-of-sight signal and a surface wave to cancel. The Non-Cutoff Frequency Selective Surface ground plane can be a metal plate with a plurality of corrugations. The corrugations can be concentric rings, each corrugation having a predetermined height and a predetermined spacing from adjacent corrugations.
