1. An antenna array comprising:
- an array of radiators; and
a substrate disposed below said array of radiators for reflecting incident energy radiated by said array, said substrate comprising a layer of dielectric photonic band gap material, said layer comprising a periodic structure of nonintersecting voids formed in said dielectric material to form a diamond lattice void structure emulating an atomic diamond lattice structure, said substrate fabricated without resonant defects in said periodic structure of voids.

Abstract
A diamond lattice structure is employed as a ground plane in an array antenna system. The ground plane structure reflects incident energy radiated by the antenna radiating elements. The structure is fabricated from a layer of dielectric photonic band gap material in which a periodic void structure is defined. The void diameter is selected to maximize the void volume within the structure. Methods of constructing the ground plane are described.
