Quick-Decision Method to Improve the Electromagnetic Compatibility Performance of Multi-Antenna System

This paper presents a method to evaluate estimated coupling degree value of all available antenna layout schemes for vehicular system. In the proposed method, all possible antenna layout schemes located on installable positions of platform for antennas are required to analyze, and every antenna is supposed to be paired with rest ones in each scheme. According to the performance analysis and spectrum analysis of the system, each pair of antennas is weighted by the effects of the interference between them to the system. With commercial electromagnetic simulation software and numeric post-process, it is possible to determine the lowest interference coupling antenna layout scheme for the vehicular system based on the weight factors. For validating the feasibility of this method, an example application is demonstrated by using actual field test data.
