摘　　要：车体及地面对车载天线性能的影响关系着车载通信系统的性能优劣,车载天线辐射方向图可以直观地表示天线的收发性能,因此对车载天线的辐射方向图进行研究具有工程价值。文中应用一致性几何绕射理论进行定性分析,然后采用基于矩量法(MOM)的FEKO软件,仿真分析了有限大平面上的鞭状天线以及某装甲车载鞭状通讯天线,位于车体不同位置时对其方向图的影响。研究结果对车载天线优化配置设计有一定参考价值。An effect of vehicular body and ground on vehicular antenna performance is related to performance of the vehicle communication system. Since the antenna transceiving performance can be directly represented with vehicular antenna radiation pattern, studying on vehicular antenna＇ s radiation pattern provides engineering applicable value. The Uniform Geometrical Theory of Diffraction （UTD） is used to perform qualitative analysis, and then, FEKO software based on MOMs is employed to simulate and analyze effect of whip antenna on the finite spacious plane and of a certain armored vehicular whip communication antenna on its pattern while the antennas are in different position of vehicle body. The studied results have a certain reference value for optimizing configuration of vehicular antennas.
