摘要
研究一种工作在C频段(5.25GHz^5.75GHz)的双线极化高隔离度微带天线,天线由2×2微带缝隙耦合天线阵列及其馈电网络组成。使用HFSS仿真软件对该天线进行仿真和优化,得到了较好的结果,在整个频段内驻波比低于1.30,隔离度大于30dB,天线在5.5GHz的水平极化增益达到13.53dB,垂直极化增益达到13.8dB。与常规的双线极化微带天线相比,该天线具有高隔离度、高增益的特点。
In this paper,a dual-polarization high isolation microstrip antenna working at C-band is presented.This antenna array is synthesized by 2×2 aperture-coupled microstrip antennas and the feed network.On the basis of Ansoft HFSS software,this antenna is analyzed and optimized.Some good results are presented.The VSWR is less than 1.30 during the frequency range of 5.25~5.75GHz.The isolation is better than 30dB.The gain of horizontal polarization reaches 13.53dB and the gain of vertical polarization is 13.8dB at 5.5GHz.Compared with the conventional dual-polarization microstrip antenna,this antenna has better isolation and high-gain characteristics.
