摘要
利用仿真软件建立GPS天线带金属板的仿真模型,分析天线的辐射方向图,并通过实际测试GPS天线带金属板时的辐射方向图进行验证。天线带金属板的仿真与实测结果能够较好地吻合,说明可以通过数值仿真分析预测天线的辐射性能,减少天线测试成本,并在整车设计阶段采取相应的优化措施。
The simulation model of the GPS antenna with metal plate is established by using the simulation software to analyze the radiation pattern of the antenna, and the radiation pattern of the GPS antenna with the metal plate is tested and verified. The simulation results of the antenna with plate are in good agreement with the measured results. It shows that the radiation performance of the antenna can be predicted by numerical simulation, and the cost of antenna testing can be reduced, and then the corresponding optimization measures can be taken in the design stage of the whole vehicle.
