【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。更多还原

【Abstract】 In the paper,a novel Ku-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.更多还原
