| 摘 要： | 多模圆锥喇叭天线是一种应用较广的新型高效率喇叭天线,合理设计的多模圆锥喇叭天线,它的方向图可以得到很好的等化性能,所以被广泛应用于反射镜初级馈源和实验室标准天线等。但是,设计的多模圆锥喇叭波束宽度(-3dB)较窄,喇叭口径在5个波长左右。本文在传统设计方法的基础上,对多模圆锥喇叭天线采用计算机辅助设计,避免了人工计算带来的误差,而且设计范围更加灵活。文章较详细地介绍了设计方法和计算框图,最后给出了分析实例,并具体设计了一种较宽波束的多模圆锥喇叭天线,理论计算和实测结果非常一致,证明了这种方法是行之有效的。

| Abstract: | The multiple-mode horn is a new high-efficiency antenna. It is widely used in the reflector feed system and laboratories. This paper describes a CAD technique for the analysis and the design of a multiple-mode horn. A multiple-mode horn with wide beam, low sublobe and excellent equivalent performance is designed by using the CAD technique. The theoretical result accords with the test result well. |
