System Emc Simulation

Electro-Magnetic Compatibility (EMC) simulation for communication system is a process to simulate different kinds of EMC problem in the system reasonably and effectively to meet the requirement of the system designing. EMC simulation makes the exist and potential electromagnetic interferences under control in the designing phase, it prevents the extreme high cost for the EMC problem in the last stage.This article takes a real communication vehicle system for the example, starts from the analysis of the electromagnetic features of the system, and describes the interference coupling ways and interference modes and the designing principles. After these, with the interference matrix of the system been constructed, the key points of the communication system have been designed, including the multi-antenna system layout design and optimization, antennas' gain pattern simulation, coupling between antenna and cables control. Finally, the communication vehicle system has been tested, and verified that the electromagnetic simulation is reasonable and effective. The requirements of the communication system are well satisfied.
