<p>An antenna system is disclosed that comprises a frontend portion and a backend portion connected to each other by a feed line. The frontend portion comprises multiple antennas that supply antenna signals, a first control unit for controlling the frontend portion dependent on control signals received from the backend portion, and at least one first crossover network that connects the feed line to the at least one first crossover network and the first control unit. The backend portion comprises multiple receivers, a second control unit that provides the control signals for the first control unit, and at least one second crossover network that connects the feed line to the at least one second crossover network and the receivers. The frontend and backend portions are configured to transmit via the feed line antenna signals from the frontend portion to the backend portion in certain frequency ranges and to transmit the control signals from the backend portion to the frontend portion in a frequency range other than the certain frequency ranges.</p> |
