摘　　要：环形可展开天线是星载大口径、超大口径可展开天线的理想结构形式,受到越来越多的重视和应用。目前,已经有Astromesh系列环形天线、Harris环形天线、EGS环形天线、双层桁架环形天线以及锥形桁架环形天线等多种展开形式的环形天线。不同展开形式研究主要集中在高收纳和高刚度问题,以实现环形天线的大口径和高型面精度。环形天线已经发射在轨有11个,其中10个成功展开并投入使用。随着航天技术发展对星载大口径天线需求的日益增长,环形天线具有广阔的应用前景。Perimeter truss antenna is the ideal structure form of space-borne large and supper large antenna, and has gained more and more attention and application. Currently, Various types of deployable structure of perimeter truss mesh an- tenna are developed, such as Astromesh family, Harris＇perimeter truss antenna, EGS perimeter truss antenna, double truss antenna, conical perimeter truss antenna, and so on. The study of different structure is mainly about stow volume and stiffness to realize larger aperture and higher surface precision of perimeter truss antenna. Eleven perimeter truss antennas has been launched, and ten of them is deployed to the expected position successfully. With the increasing demand of large space-borne antenna, perimeter truss mesh antenna has broad application prospect.
