Abstract

Abstract

A novel photonic-band-gap(PBG) Vlasov antenna is designed. The antenna is surrounded by a metallic PBG structure which is formed by square arrays of metal posts. The lowest global band gap of the two-dimensional PBG structure is determined numerically, and the gap is used to reflect and focus the antenna radiation. By numerical computation and experimental measurement, the radiation patterns of the PBG Vlasov antenna have been presented. Moreover, the numerical and experimental results both show that the maximum gain of the PBG antenna has a 2~3 dB addition.
