Analysis Of Coupling Interference Between Antennas On Multi-vehicular System In Complex Terrain

The typical EMI among the antennas of multi-vehicle was studied through communication antenna in this thesis. Firstly, the basic electric wave propagating theory for analyzing EMI among vehicles was given. Then the electric wave propagating mold with simplicity and utilities was made basing on three kinds of typical outdoor terrains. The radiation field of these terrains was calculated basing on the mold. Calculation method for multi-vehicle was given due to the radiation may be added by the radiation of serial transmitting antennas. The complex electromagnetic field was verified through typical cases. Then the mold for analyzing the coupling among vehicles was made through the calculated radiation field. The varieties of couple for different terrain and different frequency among vehicles were calculated through serial calculation cases. It also gave instructive referenced conclusion for predicting couple interference between antennas among multi-vehicle system. This is the point of invention in this thesis. The realization of the software which was called"the software for analyzing EMC for vehicle communication"made by our own team was emphasized at last.
