Application of the Translated-SWE Algorithm for the Characterization of Antennas Installed on Cars Using a Minimum Number of Samples

Automotive antenna measurements are increasingly demanding.

Modern cars are equipped with a large number of integrated antennas, spanning a wide frequency range for a large number of applications. Integrated antennas are strongly coupled with the structure, final testing are thus performed on the vehicle to accurately determine the performance. In this paper, the Translated-SWE is applied to typical automotive measurements scenarios of antennas in displaced positions on vehicles. Sampling guidelines for full vehicle testing using this method are presented for the first time. Measurement accuracy is investigated experimentally on a 1:12 scaled vehicle with integrated antenna in a standard multi-probe system.
