摘　　要：为满足测量船未来深空探测测控任务的需求,设计了三频段合用的波束波导天线。通过计算各频段在4种情况下的波束不一致及增益损失,分析了多频同时工作时电轴不一致对天线性能的影响,提出了天线尽量跟踪在高频段的使用建议,对实际应用具有极大意义。Shipbome tri-band beam wavegnide antenna is designed to satisfy the need of deep-space rIT＆C tasks. By computing beam inconsistency and gain loss for each band in four different conditions, the impact of electrical axis inconsistency on performance is analyzed in simultaneous operation at S/X/Ka-band. Suggestions for high frequency tracking are given, which is meaningful for practical applications.
