Abstract:
1. An antenna system, comprising: a ground plane; an array of antennas affixed to said ground plane, wherein each of said antennas includes a stack of antenna elements, and each said antenna element includes a radio frequency element affixed to a dielectric layer, and wherein said array of antennas comprises a plurality of sub-antenna systems, and wherein each of said plurality of sub-antenna systems has a combined effective radiating area for receiving RF energy associated with wavelengths having center wavelengths corresponding to center wavelengths of said antennas; a dielectric spacer affixed to said array of antennas; and a frequency selective structure affixed to said dielectric spacer and having a frequency selective surface, wherein said frequency selective surface is configured to reflect RF energy other than RF energy associated with wavelengths having center wavelengths corresponding to center wavelengths of said antennas.
