| 摘 要： | 研究了采用介质盖板组成的Fabry-Perot (F-P)谐振器结构的宽频带高增益平面印刷天线.比较了不同结构参数对天线性能的影响,并在此基础上通过引入二维光子带隙(PBG)结构,提出了两种既能提高增益、又能减小背向辐射的新型结构.通过软件仿真计算和实验,都验证了这两种结构的天线具有较好的实际应用性能.

| Abstract: | A broadband and high-gain printed antenna constructed from Fabry-Perot cavity with dielectric covers is investigated. Based on a systematic comparison study for dependency of antenna performances on the structure parameters, it is found that both the directive gain and front-to-back ratio can be enhanced by means of employing dielectric 2-D photonic bandgap (PBG) plates as covers. Two prototype models are designed, simulated, and tested, the results meet the expected performances for practical application. |
