A Hemi-Spherical Near-Field System for Automotive Antenna Testing

Authors: Pieter N. Betjes, Dieter Pototzki, Daniël Janse van Rensburg

A hemi-spherical near-field test system with added far-field capability is described. The facility has been constructed for the characterization of automotive antennas. The test system consists of an 11m tall dielectric gantry, a 6.5m diameter in-ground turntable and a 28m-diameter radome enclosure. Special software required to compensate for the reflectivity in the facility and the hemi-spherical truncation was developed and forms an integral part of this test system. The characteristics of this facility are described in this paper and measured data is presented.
