Abstract

In a radio station for mobile communication systems, the reception branches of at least two antenna units having different polarization are monitored in order to acquire statements about the polarization direction of the incident wave. Corresponding to the polarization direction of the incident wave, an adaptive fashioning of the radiation characteristic ensues, this fashioning the polarization direction of the emitted wave according to the weighting of the reception signals of the reception branches for the same communication connection. The connection from a base station to a mobile station in a mobile communication system therefore can be improved with an inventive radio station.
