An antenna diversity system for radio reception for motor vehicles, which comprises a multi-antenna system having several antennas with antenna feed lines. There can be a diversity switching device for selection of a different reception signal, and an evaluation circuit which evaluates the reception quality of the reception signal just arriving at the receiver. This evaluation circuit is designed to bring a different reception signal in terms of diversity to the receiver if interference occurs, by switching over. This design also includes at least one phase rotation device which is disposed along at least one of the signal paths.
