Low conductivity frequency selective surfaces for a fabry perot cavity antenna configuration

Abstract

Embodiments of an antenna are provided. The antenna has a substrate with a first major surface and a second major surface. A ground plane is spatially disposed a first distance from the second major surface of the substrate, and a patch array is disposed on the second major surface between the substrate and the ground plane. Patches of the patch array are made of a material having a conductivity of 1×106 S/m or more, and the patches of the patch array are printed onto the second major surface of the substrate.

Dependencies are inferred from the claim text.
