摘要
反射阵天线具有平面结构、低成本、易于展开、灵活的波束形状等优点,兼具反射面天线和相控阵天线的若干优点。随着配备反射天线的ISARA、MarCO等立方体卫星相继成功在轨验证,反射阵天线的技术成熟度得以提升并且逐渐获得航天应用领域的认可。反射阵天线正在成为一种非常有潜力的高性价比星载天线形式。首先简要介绍了反射阵天线的基本原理、技术特点以及研究历程,其次重点介绍了星载反射阵的论证案例与在轨演示验证试验,最后归纳总结了星载反射阵天线未来的发展趋势,为我国后续开展星载反射阵天线技术应用提供技术参考。
Reflectarray antenna combines several advantages of reflector antenna and phased array antenna,which is with the advantages of flat structure,low cost,easy deployment,and flexibly patterns.With the successful on-orbit demonstrations of ISARA and MarCO equipped with reflectarray antennas,the technology readiness level of reflectarray is significantly increased.Reflectarray attracts more and more attentions from aerospace application area,and it is becoming a potential space-borne antenna form with high price-performance ratio.Firstly,the fundamentals and technical features of reflectarrays are presented.Secondly,the cases and demonstration experiments of space-borne reflectarrays are discussed.Finally,the development trends of space-borne reflectarrays are summarized,which provides a reference for the further application of space-borne reflectarray in China.
