摘要:
通过对频率选择表面的分析,提出一种用于设计部分反射表面(PRS)的方法.该方法可使所设计PRS结构的反射相位在设计频率处产生跃变,并使PRS结构与金属地面构成的Fabry-Perot谐振腔在该PRS谐振频率两端产生两个新的谐振频率,从而实现双波段共享孔径Fabry-Perot谐振天线.设计实例的测试结果表明:当工作频率为11.5,13.2 GHz时,其峰值增益分别为16.2,15.98 dBi,工作带宽分别为5.5%,3.2%.
Abstract:
A method is proposed for the design of partially reflective surfaces(PRS)through the analysis and study on frequency selective surfaces. Using this method, the reflection phase of the designed partially reflective surface will have a sharp increase, resulting in two new resonant frequencies in the Fabry-Perot cavity formed by the PRS and the metallic ground, at the two sides of resonant frequency of the PRS, making it feasibility the dual-band shared-aperture Fabry-Perot resonator antenna. The measured results of the prototype show that the peak gains are 16.2 dBi and 15.98 dBi and the bandwidths are 5.5% and 3.2% working frequencies at 11.5 GHz and 13.2 GHz, respectively.
