Abstract :
A parametric study of the roof geometry and roof rack crossbar interactions with a multi-antenna module is presented. The effects of varying roof curvatures on the antenna performance are analyzed and compared to a flat roof. In addition, roof rack interactions for varying roof rack crossbar locations relative to the antenna are studied for different roof curvature cases. The results for GPS and SDARS will be presented.
