    • A deployable antenna which has a larger aperture diameter by four-side links provided in at least three stages and which includes: six deployment link mechanisms (20) arranged radially from a central shaft so as to support an outer edge portion of a flexible reflector mirror surface; and one deployment driving mechanism (30) arranged at a lower portion of a center of arrangement of the six deployment link mechanisms, for unfolding the six deployment link mechanisms. Each of the six deployment link mechanisms includes a first four-side link (5), a second four-side link (6), and a third four-side link (7) arranged in an order from a position of the central shaft, around which the six deployment link mechanisms are arranged, toward an outer side of the each of the six deployment link mechanisms so that the each of the six deployment link mechanisms is structured to be foldable in three stages.
    • 一种可展开的天线,其具有通过设置在至少三个级中的四侧链节具有较大孔径的直径,并且包括:从中心轴径向布置的六个展开连杆机构(20),以支撑柔性反射镜的外缘部分 表面; 和一个部署驱动机构(30),其布置在六个部署链接机构的排列中心的下部,用于展开六个部署链接机构。 六个展开连杆机构中的每一个包括从中心轴的位置起依次布置的第一四侧连杆(5),第二四侧连杆(6)和第三四侧连杆(7) 所述六个部署链接机构围绕所述六个部署链接机构排列,朝向所述六个部署链接机构中的每一个的外侧,使得所述六个部署链接机构中的每一个被构造成三级可折叠。
