中文摘要:
      为解决大口径太赫兹反射面天线工程实现的难题,提出了一套口径2.5 m的星载太赫兹天线系统。该天线由大口径反射面天线和准光学馈电网络组成,可以接收183 GHz微波电磁信号。详细介绍了天线系统电性能仿真分析与大口径反射器的结构方案,对加工完成的大口径太赫兹天线系统进行了电性能测试,实测天线主波束效率达到90.2%,能够满足静止轨道卫星载荷的应用需求。
英文摘要:
      A THz space-borne reflector antenna with an aperture of 2.5 m is presented. The antenna, which could receive electromagnetic signals at 183 GHz, is composed of the reflector antenna and quasi-optical feeding network. Its electrical performance is given, and the structural scheme is presented as well. The measurement of main beam efficiency achieves 90.2%, which could meet the specification of the GEO remote sensing satellites. It realizes a space-borne reflector antenna operating at terahertz frequency.
