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.
