Summary:
The purpose of this paper is to analyze the influence of Photonic Crystal Band-Gap(PBG) structure to the patch antenna. The method of Finite Difference Time Domain (FDTD) was used, and a dual-band patch antenna was presented. We compared two simulated antennas, one of which is based on PBG structure. By analyzing the antennas’ parameters such as S11, Radiation Pattern, and resonant frequency, we found that its directivity and gain were improved by adding the PBG structure. Besides, the characteristics of the resonant frequencies are changed accordingly. Due to these advantages, the application of photonic crystal patch antennas will be extended in various areas such as mobile communication, satellite communication, aviation, et al.
