摘　　要：设计了一种0．8～2．5GHz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。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.
