摘要： <正> 航天器天线亦称空间飞行器天线,用于卫星、飞船、空间站和深空探测器。天线按功能分类有遥测、指令、跟踪、测速、数据中继、通信广播、科学探测、遥感、测向、交会雷达、着陆导航等等,其型式多种多样,工作频率从甚低频到毫米波段。航天器天线有时比航天器本体大得多(例如ATS—6,TDRS),有时几乎就是航天器大部分表面(例如Transit-1)。

Abstract: This Paper Presents the Spacecraft antenna characteristics such as the beam types, polarization of waves and antennas, space environment constraints and the relations between antennas and spacecraft system arrangement. The new progress of spacecraft antenna techniques, such as muhibeam antennas, frequency spectrum reuse, adaptive techniques, multiuse of antennas, deployable antennas, CAD of antennas, composite materials and new technigues usedin measuremants are illustrated.
