摘　　要：从系统角度出发,结合实际工程应用中对GPS信标接收天线宽波束、小型化、集成化需求,设计了一副圆极化三频信标接收天线,重点进行了小型化、一体化设计,并应用电磁仿真软件Feko进行了仿真优化,设计中充分考虑了金属支撑管、安装地板对天线性能的影响。严格按照优化设计结果进行了天线加工与组装调试,并进行了方向图、增益测试,测试结果与仿真优化结果良好吻合,研究成果可直接应用于三频GPS信标接收系统。Combining with practical engineering application requirements for the wide beam, miniaturization and integration of GPS beacon receiving antenna,a compact type of circular polarized tri-band beacon antenna used for ground reeeiving is designed from the view of aetual system.This paper mainly focuses on minimized and integrated optimization design using the simulation software of Feko. The design takes full account of the impacts of the metal support tube and the metallic mounting ground plate on the performance of the antenna.In strict accordance with the optimization design results,a tri-band beacon verification antenna is machined, and then the radia- tion pattern and gain are tested. The test results are in good agreement with the design and simulation. The research results can be direetly applied to the tri-band GPS heacon receiving system.
