| 摘 要： | 采用十字缝隙耦合,层叠贴片和微带线馈电的结构形式,设计了一种适用于Ku波段的宽频带双极化微带天线。利用电磁仿真软件CST 5.0微波工作室对天线的电特性进行仿真优化,并制作了实物模型,实测结果和仿真结果吻合良好。两馈电端口回波损耗小于-10 dB的阻抗带宽分别达到34.2%和28.7%,端口隔离度高于21.4 dB。

| Abstract: | A wideband cross shaped slot-coupled dual-polarized microstrip antenna at Ku-band is designed.The antenna uses a structrue of cross-shaped slot coupling,stacked patches and microstrip fed.The parameters of antenna are simulated and optimised by the simulator of CST5.0.The experimental prototype is also made.The measured results agree well with the simulated results.Bandwidths for each port about 34.2% and 28.7% for Return Loss less than-10 dB are obtained.The isolation between the two ports is better than 21.4 dB. |
