S／X／Ka三频段天线电轴不一致性对天线性能的影响

内容简介：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。

Abstract： Shipborne tri-band beam waveguide antenna is designed to satisfy the need of deep-space TT&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.
