Abstract
Antenna arrays are expected to be widely used for future mobile radio applications. Therefore implementation issues are a matter of concern. Since real antenna arrays suffer from different impairments, sophisticated calibration procedures are required in order to enhance the performance. For that aim a promising calibration approach is described Its performance has been verified by simulations and measurements. Especially, the application for the direction of arrival estimation in wideband radio vector channel sounders is addressed.
