摘　　要：重点介绍了对车载FM玻璃天线仿真技术的应用开发,通过仿真与测试新型天线的对标结果,证实了新型玻璃天线及其整车电磁仿真模型的可靠性。首先通过FEKO软件中的Windscreen模式,运用MoM(矩量法)对标建立了两侧窗FM玻璃天线电磁模型;然后建立了整车模型并进行有效简化,并利用该模型的电磁仿真结果,评估了某车型加装工具箱和爬梯后不同布置方案对天线性能的影响;最后通过暗室信号测试、外场信号测试、外场听感测试三个维度的测试进行对比,验证了仿真结果的准确性。这项仿真技术的研究,更直观地预测了天线及整车的电磁场分布,对后续正向研发新型车载无线系统具有重要意义。This paper focuses on the development of the vehicle-mounted FM glass antenna simulation technology.The reliability of the EM simulation model of glass antenna and glass antenna on vehicle is illustrated by the consistency of simulation and measurement results.In this paper,the electromagnetic models of the glass antennas on both sides as well as the effectively simplified vehicle were firstly built by using Windscreen function in FEKO,then calculated by MoM(Method of Moments)algorithm.The developed electromagnetic model was further used for the evaluation of the antenna performance on a particular fully equipped certain kind of vehicle.The reliability of the simulation results is further compared with the results obtained via three measurement approaches respectively:the dark room signal test,external field signal test and external field audio-sensory test.The application of this antenna and entire vehicle simulation technology can intuitively make accurate prediction on the EM field distribution,exhibiting great guiding significance for the performance evaluation subsequent forward research and development on new wireless communication devices.
