通信天线布局电磁仿真设计

摘要

In the process of the electromagnetic compatibility(EMC) design of vehicle-borne commu-nication system, the antennas layout is critical to system EMC for the realization of electromagnetic compatibility as one of the important factors. According to the analysis of two layout schemes,the cor-responding models based on EMC theory are built and simulated using CST for electromagnetic compa-tibility research. Considering the hazards of electromagnetic radiation to personnel and the coupling be-tween antennas,the better antennas positions were obtained by comparing the simulation results of two different kinds of layout so as to improve EMC performance in terms of systemic compatibility so that EMC simulation may provide references for the design and application of communication antennas layout.%在车载通信系统的电磁兼容设计过程中,天线布局设计是实现系统电磁兼容的重要内容之一.通过对某通信系统两种天线布局方案的分析,建立相应电磁模型,使用CST软件进行电磁兼容性仿真研究.通过分析天线对人员的辐射危害,以及通信天线间的相互影响,对两种方案进行了比较,提出天线布局设计的优选方案,提高系统的兼容性,为通信天线的布局设计和应用提供参考.
