基于光子晶体PBG结构的微带天线优化研究
Optimizating microstrip antenna based on photonic crystal PBG structure
摘要
Abstract
To ensure the operating frequency of antenna locating on photonic crystal band gap range, a rectangular micros-trip antenna model is analyzed and calculated. Photonic crystal as substrate is used, the diameter and the distance of air gaps are changed between the two gaps, the feed position is optimized, and HFSS12 electromagnetic simulation software is used to build model, scan, optimize and analyze. The best transmission performance would be realized. The return loss of optimization antenna reduced -31.24 dB than the original, the relative bandwidth ( VSWR ≤ 2) reaches 5.3% , the maximum gain of antenna radiation direction reaches 25. 3 dB. The simulation results show that the photonic crystal PBG structure could greatly improve the transmission performance of microstrip antenna.关键词
