0.8~2.5 GHz双极化四脊圆锥喇叭天线设计

摘要

A 0.8~2.5 GHz broadband dual⁃polarized quadruple⁃ridge conical horn antenna is designed in this paper. The quadruple⁃ridge design of the antenna is regarded as two symmetrical double⁃ridge conical horns. Based on the known electromag⁃netic simulation software HFSS,which covers parameter and structure optimization,VSWR,isolation,gain,and directional dia⁃gram of the designed horn antenna can be worked out. The results show that the optimized antenna is of low⁃VSWR,high isola⁃tion and improved directional diagram. It is valuable for engineering design as a reference.%　　设计了一种0.8~2.5 GHz双极化四脊圆锥喇叭天线。四脊喇叭天线的设计可以看成对称的两个双脊喇叭天线，利用HFSS电磁仿真软件对天线的参数及结构进行优化，计算了天线的驻波比、隔离度、增益和方向图等参数。结果表明，优化后的天线满足低驻波比，高隔离度，好方向图等特点，对工程设计具有一定的参考价值。
