| 摘 要： | 设计了一种宽带宽角双极化相控阵天线单元,该天线单元采用指数渐变开槽天线形式,并设计了金属匹配柱安装在双极化天线单元之间,保证了开槽天线的接地连续问题。依次给出了该双极化天线单元的仿真设计、阵列样机的性能测试,从仿真和测试结果中可以看出,该双极化天线在3倍频程带宽内具有良好的匹配和辐射特性,并且能实现大角度二维扫描。该双极化天线单元具有宽频带、体积小、结构简单等特点,适于用作宽带宽角扫描相控阵天线的阵列单元。

| Abstract: | A new type of antenna element for wide-band wide-angle dual-polarized phased array antennas is presented.This dual-polarized antenna element is tapered slot type of antenna,and achieves electrical connection by using metallic posts.Simulation results and measured results demonstrate this new antenna element has good performance with 3∶ 1 bandwidth for a wide angle scan.This new element has wide-band,small volume and simple structure,and is suitable for wide-band wide-angle dual-polarized phased arrays. |
