摘要
采用传输矩阵理论,分析了带缺陷的一维光子晶体的传输特性,随缺陷层厚度和周期数变化的情况,并把这种结构应用于微带天线中,通过HFSS软件仿真,结果表明,相比于普通的微带天线,光子晶体天线的谐振频率有所降低,方向性得到了很大的改善。
Transfer matrix method （TMM） is used to analyed transmission properties of one-dimensional photonic crystal with defect mode, and its situation of properties are study as the change of defect thickness and the number of period, we also apply this structure into microwave antenna, the results of simulation by Ansoft HFSS indicate that compared to normal microstrip antenna, the resonant frequence of photonic crystals antenna is reduced a little, and the directivity is improved efficiently.
