摘要
高通量卫星能够大幅提升系统的通信容量,而高增益多点波束天线是高通量卫星实现高数据吞吐量的核心。文章首先介绍了星载多波束天线的分类,然后着重介绍了典型的国外高轨道高通量卫星中的多波束天线技术,梳理总结了目前高通量卫星多波束天线的关键技术和发展趋势,为我国后续开展更大容量星载多波束天线技术的研究提供参考。
High-throughput satellites(HTS) can greatly enhance the overall system communication capacity and high gain multi-point beam antennas are the key to HTS systems. This paper introduces the classification of spaceborne multibeam antennas and presents the current state of multibeam antennas for the typical GEO HTS systems. Finally,the key technologies and development trends of multibeam antennas are summarized, which provides a reference for the further larger capacity spaceborne multibeam antenna in China.
