Fabry-Perot天线设计的系统方法

内容简介：利用接收工作状态模型法，对法布里珀罗（Fabry-Perot，FP）型微带天线进行了系统方法设计与研究，并用电磁场分布理论，从全新的角度解释了 FP 谐振天线可获得高方向性的原因。同时，设计了包括频率选择性表面、介电常数分别为10．2和4．4的不同类别的介质板在内的3种不同盖板，并将其应用在 FP 天线上。在此基础上，对 FP 天线的辐射性能、方向性系数和增益都进行了测算和对比分析，并同时计算了其口面利用效率。

Abstract：A systematic approach is applied to the design and research of Fabry-Perot(FP)microstrip anten-na with the receive mode structure.The distribution theory of electromagnetic field is used to interpret why FP resonator antenna can achieve directivity enhancement in a revolutionary view.Meanwhile,three different su-perstrates including frequency selective surface and dielectric slabs (εr =10.2 andεr =4.4)are designed and ap-plied to FP antennas.Based on that,the radiation features,directivity factor and gain of FP antenna are compu-ted and analyzed with comparison.The utilization efficiency of actinal surface of FP antenna is also calculated.
