| 摘 要： | 该文基于喇叭天线的基本理论,研究了影响喇叭天线截止频率的因素,确定了双脊喇叭天线的基本尺寸,最后利用HFSS软件进行喇叭天线的建模仿真优化,确定了6～18 GHz超宽带双脊喇叭天线的最终尺寸.仿真数据和测试结果吻合的很好,在整个频率范围内增益大于G＞10 dB,驻波比小于VSWR＜1.6,它的主波束在整个频段几乎没有分裂,现已应用于电子对抗领域.

| Abstract: | The factors of influencing the cut-off frequency of the horn antenna have been studied based on the basic theory of the horn antenna in this paper.The size of the double-ridge antenna has been identified.The modelling and optimization of the horn antenna have been carried out by using the HFSS software,thus the fiinal dimension of a UWB double-ridge horm antenna with 6~18 GHz frequency has been determined.The simulation results are in good agreement with the measured ones.The antenna has the features of the... |
