| 摘 要： | 介绍用于Φ7.3 m Cassegrain天线的高功率馈源喇叭的设计。为使E面和H面方向图在照射区域内具有高的等化度，选择双模圆锥喇叭作为馈源的结构形式。由于高功率源采用BJ-32波导输出信号，故馈源系统中还应包含一个矩形到圆形的模式转换器，将TE10模转换为TE11模。设计了双模圆锥喇叭和模式转换器，并进行了功率容量估算。测试结果表明，所设计的馈源达到了设计要求，理论计算结果和实验测试数据吻合良好。 |

| Abstract: | This paper presents a high power feed system for 7.3 m Cassegrain antenna. In order to make E and H patterns of the feed equal in the illuminated area, the dual-mode conical horn is chosen as the feed form. Since the high power signal is transmitted from the BJ-32 waveguide, a mode convertor from rectangular TE10 mode to circular TE11 mode in the feed system should be provided. The feed system, including a dual-mode conical horn and a mode convertor, was designed, manufactured, and measured. The measured results indicate that the feed system achieves the design goal, and the measured results agree well with the theoretical results. |
