双极化微带缝隙天线单元研究

摘要

研究了一种S波段双极化十字缝隙天线单元,利用电磁仿真软件仿真分析了缝隙宽度对驻波和交叉极化性能的影响。仿真结果表明,天线的驻波和方向图特性较好,增大缝宽展宽驻波带宽但没有明显提高天线的交叉极化电平。测试结果与仿真结果基本吻合。%A study on the S-band dual-polarized cross slot antenna elements is made.The effects of the slot width on the performances of the VSWR and the cross polarization are simulated and analyzed through the EM simulation software.The simulation results show tha
