Abstract: A two dimensional periodic pattern of capacitive and inductive elements defined in the surface of a metal sheet are provided by a plurality of conductive patches each connected to a conductive back plane sheet between which an insulating dielectric is disposed. The elements acts to suppress surface currents in the surface defined by them. In particular, the array forms a ground plane mesh for use in combination with an antenna.

This eliminates surface currents between the antenna and the ground plane thereby reducing power loss and unwanted coupling between neighboring antennae.
