摘　　要：现有的馈源设计方法设计出的馈源工作频段少,不能满足"北斗"导航天线馈源的要求。为此,在对模式展开法和模式匹配法理论研究分析基础上,提出了优化双槽深波纹喇叭槽参数的设计思路。分析和试验结果表明,该"北斗"导航天线馈源增加了工作频段,具有良好的电气性能,满足了"北斗"天线系统的需求,验证了设计方法的有效性。The frequency band of feed designed by the current method is not enough to meet the requirements of the Beidou navigation antenna.To solve the problem,by employing the mode expansion and mode matching technique,an optimization design of the dual-slot corrugated horn is proposed.The theoretical analysis and test results show that the Beidou navigation antenna feed increases frequency band and has good electrical performance,which satisfies all the requirements of the Beidou navigation antenna system.The design has been verified by experiments.
