摘要
天线作为通信、导航、雷达、电视、遥控遥测、航天成像等各种无线电系统中不可或缺的设备,其工作性能的好坏至关重要。相比于传统天线,微带天线不仅体积小,重量轻,低剖面,易共形,而且易集成,成本低,适合批量生产,此外还兼备电性能多样化等优势。首先阐述了低副瓣天线的理论方法[1],通过经典理论分析,得到初步参数,然后用三维电磁仿真软件HFSS进行了仿真,优化了贴片及馈电网络等各参数。采用对单元的同相不等幅电流分布馈电的方法设计出了16×16单元的高增益低副瓣微带阵列天线,大小为400mm×400mm×0.8mm。
As the indispensable part in radio systems,such as communication,navigation,radar,telecontrol and telemetering,Space imaging,the performance of antenna is very important. Compared with traditional antennas,microstrip antenna has many advantages,such as miniaturization,light weight,low profile,easily integrated,and low cost,suitable for mass production. Besides,it also can get diverse electrical performances. First expounds the method of low sidelobe theory,and by the analysis of the classical theory,we get the preliminary parameters of the design. Then,simulated and optimized the patch and feed network and so on various parameters use the 3D electromagnetic simulation software HFSS. By feeding the antenna with the same phase and different amplitude current we designed a 16 ×16 units array microstrip antenna with high gain and low sidelobe,with the size as 400mm＊400mm＊0.8mm.
