基于TEM喇叭天线的结构特点,用两根弯曲的窄带代替基本模型中的上板,设计了一种飘带喇叭天线。该设计不仅有效地提高了天线的低频利用率,并且实现了天线的轻量化。通过对飘带结构进行进一步改进,利用AnsoftHFSS仿真软件对模型进行了分析。结果表明,改进后的飘带喇叭天线不但有较好的超宽带性能,而且其辐射性能也有了较大提高。经过优化,改进的飘带喇叭天线可以实现在0.1~4 GHz频率范围内VSWR〈2.0。

Based on the structural characteristics of TEM horn antenna,the ribbon horn antenna is designed with two curved narrow ribbons superseding the top plate of the basic model.The ribbon structure can not only improve the utilization of the low frequency effectively,but also reduce the weight of the antenna greatly.Through further improvement of the structure of the ribbon,the analysis is obtained by the HFSS simulating software.The results show that the antenna has good ultra-wideband performance and the radiation performance is also greatly improved.The frequency band of the improved ribbon horn antenna is 0.1GHz to 4GHz for VSWR less than 2.0 via optimization.
