Abstract
Base-driven whip antenna is negatively affected by metallic car body seriously because car body plays a role of radiating portion of the antenna. The overall goal of this study is to analyse some important electromagnetic characteristics of whip antenna mounted on the vehicle. In this paper vehicle electromagnetic modeling based antenna modeling was presented. Whip antennas installed on different positions in the modeling were analysed based on method of moments (MoM) with the purpose of showing the impact of the car body on the performance of the whip antenna. The optimal antenna location was determined by performance of antenna coupling S-parameter and radiation field gain direction figure in given frequency band. Through the analysis we can know that the optimal location of the whip antenna is the middle of the top part of car body. It can get good performance both omni-directional work and radiation power. Another area of interest is the value of coupling between two antennas. The study showed that antenna coupling degree is determined by distance of installation position and dimension of an antenna.
