摘　　要：为了获得可应用于工程的具备理想特性的天线,在Ku波段设计了一种平面结构的微带阵列天线。在设计微带天线的辐射贴片结构基础上完成了馈电网络和八元阵列天线的设计,通过CST仿真软件构建阵列天线模型,并优化天线的尺寸参数,得到天线的S参数、驻波特性和增益方向图等特性。仿真结果表明,该微带阵列天线具有高增益和低副瓣特性,且方向性良好,具有较高的实用价值,可用于天线工程。In order to obtain an antenna with ideal characteristics that can be applied to engineering,a planar structured microstrip array antenna was designed in the Ku band.The radiation patch structure of the microstrip antenna is designed.On this basis,the design of the feed network and the 8-element array antenna is completed.The array antenna model is constructed by CST simulation software,and the size parameters of the antenna are optimized.Finally,the antenna S parameters,standing wave characteristics and gain pattern are obtained.Simulation results show that the microstrip array antenna has high gain and low side lobe characteristics,and has good directivity,and has high practical value,and can be used in antenna engineering.
