Abstract

This paper describes an electric-field uniformity evaluation of an automotive manufacturerpsilas vehicular antenna range. Dipole measurements, vehicle gain measurements, ultra wideband measurements, and two independent electromagnetic simulations were performed to determine field uniformity characteristics of the antenna range. The simulations and measurements indicated that the turntable significantly influenced the sitepsilas field uniformity. It was determined that increasing the size of the metallic turntable degraded the field uniformity performance of the range. Ideally, the size of a metallic turntable should be minimized to maximize field uniformity performance.
