Abstract
An antenna system is disclosed which includes a frontend portion, a backend portion, a feed line for connecting the frontend portion and the backend portion with each other, and a control unit for controlling the frontend portion and/or backend portion. The frontend portion includes multiple antennas that supply antenna signals and at least one combiner network that connects the antennas to the feed line. The backend portion includes multiple receivers and at least one splitter network that connects the feed line to the receivers. The control unit is configured to evaluate the reception quality and adjust the at least one combiner network and/or splitter network dependent on the reception quality. The at least one combiner network combines the signals from at least two antennas in different, non-overlapping frequency ranges to form at least one combined signal thereof.
