摘　　要：在汽车通信系统中,天线的安置环境对超宽带MIMO天线性能的影响直接关系着通信的质量。采用了汽车通信系统中天线安置环境仿真模型,并研究了天线安置环境对超宽带MIMO天线在汽车通信系统中性能的影响。通过CST软件对用于汽通信系统的MIMO天线在模拟安置环境条件下进行了仿真,表明汽车通信系统中天线的安置环境对MIMO天线系统中天线1和天线2的匹配性能以及它们之间的隔离度影响都不大,结果表明该MIMO天线能很好地应用于汽车通信系统中。In the automotive communication systems,the antenna housing effect has been introduced to evaluate the performance of UWB antennas and directly influences the quality of communication.In this paper,a simulation model of housing effect is designed in presence of the approximate in-car environment,whose influence in automotive communication systems is studied.Simulation results show that the antenna housing effect in the automotive communication system has little effect on the bandwidth performance of the antenna 1 and the antenna 2 and the isolation between them.This conclusion verifies that the MIMO UWB antenna can be well appropriate for automotive communication systems.
