摘要 结合传输线理论和史密斯圆图分析,文中提出了一种利用全介质部分反射覆层构造宽带Fabry-Perot谐振腔天线的方法。所设计的覆层结构在工作频带内拥有正斜率的反射相频特性,可满足谐振腔天线的宽带谐振条件。运用该方法设计了工作于Ku频段的宽带Fabry-Perot谐振腔天线,通过仿真计算和样件加工测试验证了该方法的正确性和有效性。 A new design method of wideband Fabry-Perot resonator antenna （FPRA） is presented. A double-layered full-dielectric superstrate, which produces a reflection phase curve versus frequency with a positive slope, is used as a partially reflective surface （PRS） to enhance the gain bandwidth of the FPRA. For a physical insight, the PRS is analyzed by using the transmission line the- ory and Smith Chart. The proposed method, as well as related analysis, is validated by a practical wideband FPRA design.
