| 摘 要： | 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 antenna 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 superstrates including frequency selective surface and dielectric slabs (εr=10.2 and εr=4.4) are designed and applied to FP antennas. Based on that, the radiation features, directivity factor and gain of FP antenna are computed and analyzed with comparison. The utilization efficiency of actinal surface of FP antenna is also calculated. |
