摘　　要：运用口径耦合的馈电方式及叠层贴片形式设计出一种新型的用于Ku波段通信的双极化微带贴片天线。给出单元天线的结构及设计方法,同时探讨了各项参数对天线性能的影响。测试结果表明,单元天线端口驻波比小于2(VSWR<2)的相对带宽达到20.5%和23.7%,单元的极化隔离度低于-36.5 dB,理论计算结果与实测值一致。In the paper,a novel K u- band communication microstrip patch antenna with dual -polarized and its features are studied. Antenna unit with the dual - polarized microstrip patch and the apertures - coupled. With the design method and the experimental results to be presented. Also, the relationship between the input impedance and the structure parameters has been discussed. A prototype has been designed and tested, the measured return loss exhibits an impedance bandwidth of over 24.2 and 23.7 % for the antenna with VSWR less than two can be achieved. Good agreement has been obtained between simulation experimental results. Keyworcls ：
