摘要
对各种Fabry-Perot谐振器印刷天线结构的辐射性能进行了详细比较,从而发展了两种改进结构:采用频率选择表面(FSS)为盖板、U形缝隙矩形贴片为辐射器、以及采用普通电导体或人工磁导体(AMC)为反射板,构成Fabry-Perot谐振器的印刷天线,实现了高增益、低旁瓣电平、高前后辐射比、较宽的阻抗与增益公共频带等性能,以及低轮廓结构。
A detailed comparison of radiation performances was taken among several Fabry-Perot (F-P) resonator printed antennas, and then two improved structures of F-P resonator printed antennas are developed by using a frequency selective surface (FSS) as the cover, a U-slotted patch as the radiator and a traditional electric con- ductor or an artificial magnetic conductor (AMC) as the reflecting plate. These im- proved structures can reach good performance of high gain, low side-lobe-level (SLL), high ratio of front-to-back radiation, relative wide common bandwidth for both impedance and gain, and low profile in structure.
