一种新型的双波束指向馈源喇叭

摘要

It introduced a new feed horn. The horn reflector idea was usedin the design of the feed. The dual frequency band、 perpendicular polarity and two beam pointing properties were realized. The design idea and correction method of beam of this feed was discussed emphatically. Final, the measurement rusults of the feed horn patterns are given.%文章介绍了一种新型的馈源喇叭，这种馈源的设计，利用了喇叭反射面天线原理，实现了馈源的双频、双极化、双波束指向功能。文中重点讨论了这种喇叭的设计思想及波束特性的修正方法，给出了这种馈源喇叭特性的实际测量结果。
