摘要
针对目前卫星通信系统对天线性能、形式的需求,回顾了卫星移动通信中天线的发展历程和分类,并详细比较了不同形式低剖面动中通天线的优缺点;特别针对国外的一维和二维有源相控阵天线产品进行了详细介绍,指出了各自产品在具体使用环境中的特点,在此基础上提出了相控阵天线设计的关键技术;最后,对卫星移动通信平台中相控阵天线的发展趋势进行了展望。
According to the requirements of satellite communications on antenna performance and shape,the development of antenna for on-the-move satellite communications is firstly reviewed,the advantages as well as shortcomings of low profile on the move（OTM） antennas in different shapes are compared.Then,the 1-D and 2-D electronic scanned active phased arrays products abroad are introduced in detail.And the characteristics of these products under the condition of their deployment environment are presented,based on which,the key techniques for phased array antenna are further summarized.Finally,the development trend of phased arrays for the platform of on-the-move satellite communications is predicted.
