摘　　要：在高功率微波辐射技术中,馈源系统是天线系统的最终功率容量限定因素,因此高功率馈源系统的设计成为关键。本文设计了一种S波段高功率微波天线的馈源系统,该系统由双模圆锥喇叭和矩-圆模式转换器两部分组成。理论设计与电磁仿真和实际测试的结果基本吻合,E面和H面方向图在照射区域内等化良好(误差电平≤1dB),功率容量达到150MW,且该馈源系统已成功应用于7.3m卡塞格仑高功率微波天线。In the HPM radiation techniques, the design of HPM feed system becomes the key, because the feed system is the ultimate power limit factor of the antenna system. This paper designs a S-band feed system for HPM antenna, which consists of a dual-mode conical horn and a rectangular-circular mode convertor. The theoretical results are in good agreement with the results obtained by the simulations and measurements. Moreover, E and H patterns of the feed system are well equal in the illuminate area （error level 〈 1 dB）, and the power capacity reaches 150MW. This feed system has been successfully applied to the 7.3m Cassegrain HPM antenna.
