摘　　要：针对微小卫星应用发展过程中对星载天线提出的轻质量、高收纳比和大口径的需求,设计了一种新型剪叉式可展开薄膜天线。该设计应用剪叉式机构作为天线的骨架,以实现薄膜天线的二维收拢,能够有效提高天线的整体收纳比并扩大天线口径。运用计算机软件建立模拟样机并进行仿真分析,仿真结果验证了剪叉式机构展开的可行性和展开后结构的稳定性。A new kind of scissor deployable thin-film antenna is designed for the request of light weight,large aperture space borne antenna with efficient folding-and-deploying capability.By using scissor structure as framework of antenna,the two-dimension folding of thin-film antenna is achievable.Then the capability of folding and deploying can be improved,and the aperture can be expanded.Computer software is used to build virtual model and operatesimulation analysis,and the results prove the practicability of the scissor mechanism and the sta⁃bility of the structure after-deploying.
