中文摘要:
      基于传统的倒F型天线,设计了一种M构型的新型小型化星载自动识别系统(AIS)天线。该天线具有尺寸小、质量轻、便于星体安装等优点,天线外形尺寸仅为324 mm?60 mm?263.2 mm。采用CST MICROWAVE STUDIO电磁软件进行仿真设计,在球面近场进行实物单机测试和辐射模型星(Radiating Mockup,RM)测试。天线的仿真和实测结果一致性好,且天线方向图覆盖区域能够满足卫星AIS系统的应用需求,目前已在多颗小卫星上得到成功应用。
英文摘要:
      A novel satellite-based Automatic Identification System(AIS) antenna is proposed. The design is based on Inverted-F antenna, and M shape is utilized to achieve the miniaturization intention. The dimension of this AIS antenna is only 324 mm(L)?60 mm(W) ?263.2 mm(H). The CST MICROWAVE STUDIO is adopted for the optimized design, and performance test of the antenna element and radiating mockup is performed with the spherical near-field antenna measurements system. Simulation and measured results verify the performance of the proposed antenna, which can meet the application requirement of satellite AIS system.
