摘　　要：天线是现代汽车上经常使用的设备之一,研究天线电磁特性受车体影响的情况和不同类型天线间的干扰情况是十分重要的。建立了逼真的汽车模型,利用CST微波工作室对模型上不同位置的鞭天线电磁特性及鞭天线与PIFA天线间的耦合度进行了仿真研究,最终通过仿真结果得出最佳的天线安装位置及天线间的耦合情况。分析过程和所得到的结果可作为汽车电磁兼容研究及车载天线设计的手段和依据。Antenna has become a frequently used component electromagnetic character of antenna affected by vehicle body in modern vehicles, and it is very important to research the and the interference among the different kinds of antennas. A lifelike vehicle model was constructed, and then the electromagnetic character of whip antenna at different position on model and the coupling degree between whip antennas and PIFA were simulated using CST micro wave studio. The best antenna position and coupling between antennas were obtained by simulation results at last. The analysis process and simulation results can be ways and means for vehicle electromagnetic compatibility research and vehicle antenna＇s design.
