车载多天线系统的仿真研究

随着移动通信的发展,现在的车载系统上配置的天线数目也越来越多,如何对这些天线的位置合理布局,使相互间的影响最小成为一个急需解决的问题。使用FDTD数值仿真算法,全面分析了复杂的车载短波与超短波天线系统的电磁兼容特性,包括天线之间的隔离度,装车平台和其他天线对目标天线增益方向图的影响,为车载通信系统设计提供一种新的实用方法。

Research of Vehicular Multiple Antennas System on Simulation

With the development of the mobile communication, more and more antennas are fixed on the vehicle now. Thereby, the pivotal problem is how to ascertain the position of these antennas and reduce the influence among them. The FDTD simulation algorithm was used to calculate and analyze the EMC problems between HF and VHF in complicated vehicular multiple antennas system, including the isolation between antennas, and the gain pattern of objective antenna effected by vehicle platform and other antennas. New applied method was provided to design the communication system of the vehicle.
