摘　　要：采用十字形缝隙耦合,层叠贴片和微带线馈电的结构形式,设计了一适用于Ku波段的宽频带双极化四元微带天线阵。利用电磁仿真软件CST5.0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。两馈电端口驻波小于2的阻抗带宽分别达到20.9%和46.2%,端口隔离度高于17.5dB,天线增益11dBi。A wideband dual-polarized microstrip array antenna at Ku-Band was designed.The antenna uses a structure of cross-shaped slot coupling,stacked patches and microstrip fed.The parameters of the antenna are simulated and optimized by the simulator of CST5.0.The experimental prototype is also made.The measured results agree well with the simulated results.The bandwidth at the two ports is about 20.9% and 46.2%(for VSWR less than 2:1) respectively.The isolation between the two ports is better than 17.5dB.The simu...
