Improvement of Performance of Thick High Dielectric Patch Antennas Using Photonic Bandgap Structures

포토닉 밴드갭 구조를 이용한 두껍고 큰 유전상수 패치 안테나의 성능 향상

This paper presents that photonic bandgap structures suppressing the propagation of surface waves can improve the performance of the patch antennas on thick high dielectric constant substrate. The forbidden propagation of surface wave due to the photonic bandgap enhances the radiation efficiency and reduce the back radiation drastically with maintaining the small size and wide bandwidth of the antennas.
