摘　　要：基于TEM喇叭天线的结构特点,兼顾天线辐射性能和轻量化考虑,设计了一种"飘带"式喇叭天线,该设计用两根弯曲的窄带代替了基本模型中的上板。针对"飘带"式喇叭天线的一些重要物理尺寸,利用Ansoft HFSS仿真软件对模型进行了分析。结果表明,该结构进一步改善了喇叭天线的低频性能,展宽了天线的频带。最后分析了"飘带"式喇叭天线的各个参数与天线性能之间的关系,得到了一组优化结果。Based on the structural characteristics of TEM horn antenna, taking antenna radiation performance and light weight into account,the design of a ribbon type that two curved narrow bands supersedes the basic model on the top board. The important parameters of ribbon horn antenna such as＇physical size,which can be analyzed using Ansoft HFSS simulation software. The low- frequency characteristics of the antenna have been modified, and the band has been extended. Finally, the relationship between the various parameters of ribbon horn antenna and antenna performance has been obtained via optimized.
