摘要
本文利用有限单元法对毫米波宽带四加脊圆锥喇叭天线进行了理论分析和综合优化设计。对于这种形式的毫米波宽带天线在频率范围26—40G内的驻波分布情况进行了重点研究。并且，根据设计尺寸制作了一个实验样品，完成了有关实验，获得了满意的实验结果。
In this paper the optimization design and analysis of an millimeter-wave rectangular-circular wavegnide transformer and an millimeter-wave wide-band quadruple-ridged conical horn antenna have been gotten. The attention is concentrated on the distributing of VSWR of the antenna and its feed under the band of 26-40GHz. And using the design dimensions, an experimental sample is made. The results of the experiment is satisfied.
