The Simulation and Research on Electromagnetic Character and Coupling Degree of Vehicle Whip Antennas

Antennas have become a frequently used component in modern vehicles. It is very important to research the electromagnetic character of antenna affected by vehicle body and the interference among the antennas. In this paper, a lifelike vehicle model was construct. Then the electromagnetic character of whip antenna at different position on model and the coupling degree between antennas is simulated used CST based FIT technology. The best antenna position was 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.
