摘要
大型空间可展开天线设计是一项极具挑战性的任务,与传统天线设计相比在很多方面都有所不同。文章首先介绍了大型空间可展开天线的结构特点和分类,然后从应用业务、工作频段、发射时间、供应商和天线类型五方面总结了大型空间可展开天线的应用现状,展望了发展趋势。最后讨论了大型空间可展开天线设计的关键技术问题,包括机械、热、电和测试等技术,可供我国大型空间可展开天线的研究参考。
Large deployable space antenna design is a challenging task because it differs in many aspects from classical antenna design.In this paper,the structural features and classifications of large deployable space antennas are introduced.Then the applied situation of large deployable space antennas is summarized from five aspects： mission needs,operating frequency,launch date,providers and types.Their development trends are prospected.Finally,the key technologies are discussed including mechanical,thermal,electrical,and test technologies.The work affords some useful references for developing our own technologies of large deployable space antennas.
