A novel PBG structure for a microwave integrated circuit and a planar antenna in a telecommunication system

Abstract

Applications of the novel artificial microwave crystal, PBG, made by etching were demonstrated for the circuit as well as for the antenna. The PBG was designed using a computer program based on the FDTD method. From observation of experimental data, the improvement of the microwave and millimeter-wave circuit and of the planar antenna by combining the PBG technique were confirmed.
