Modeling And EMC Analysis Of Angled Reflector Antenna In Vehicular Multi-antenna System

This paper is mainly focused on the modeling of the angled reflector antenna in vehicular multi-antenna system based on the Method of Moment (MoM), and the corresponding Electromagnetic Compatibility (EMC) analysis.Firstly, an analysis of the EMC characteristics of the vehicular antennas is made, including the coupling effect of the vehicle to bottom feed antenna, middle feed antenna and angled reflector antenna. Also, some simulation by FEKO is made, and comes to a conclusion that the vehicle must be taken into account when we analyse the wire antennas, but do not need to be modeled when analyse the angled reflector antenna because of the high frequency, strong directivity and long distance from the vehicle.Secondly, some important modeling parameters of the angled reflector antenna are discussed, and the scheme of modeling is proposed. Then, patameter modeling of the angled reflector antenna is made using MoM, and a brief description of the means of dealing with the grid, vehicle and promotion pole is given.Finally, a detailed introduction is made of the struct and data stream design of the EMC simulation module of the angled reflector antenna. The user interface of the module is programmed, which makes the modeling and EMC analysis of the angled reflector antenna into possible. Thus, complete the EMC simulation software of the vehicular multi-antenna system. Moreover, some modeling and computation of pattern and coupling of the angled reflector antennas in vehicular system is made, and the means of reducing the coupling between angled reflector antennas is given.
