摘　　要：本文研制了一种500MHz～3.5GHz高性能宽带双极化四脊喇叭天线。首先采用化四脊喇叭天线为双脊喇叭天线的设计方法设计初步模型,然后利用HFSS对四脊喇叭天线的参数及结构进一步优化,提高了两个极化端口的驻波比性能:一方面对四脊波导各个参数对驻波比的影响进行分析,选出最优的参数组合;另一方面,结构上采用渐变结构、脊末端顶入导体杆、特制细探针馈电等设计。最终的测量结果显示,优化后的天线具备高性能:工作频带宽、方向图好,驻波比低,且两个极化端口的驻波比一致性好。A high performance 500MHz^3.5GHz broadband and dual-polarized quadruple-ridge horn antenna was designed which serves as a low frequency band feed antenna. The design process was divided into the process of preliminary design which is substituting the quadruple-ridge horn to double-ridge horn and the process of optimum design using HFSS which covers parameter and structure optimization. Firstly, The corresponding impact on the VSWR when each of the parameters changes is analyzed. Secondly, a variety of struc...
