Abstract
The invention relates to an antenna system (1) comprising several antennae (2), which can be connected to at least two receivers (4, 4') via a combination unit. According to the invention, a signal processing unit (5) for evaluating the output signals of the receivers (4, 4') and a control unit (10) are provided, by means of which at least one of the antennae can be switched to transmit mode in order to conduct a self-test. These antennae (2) transmit test signals with a test frequency that is pre-set by a first receiver (4). Said test signals are fed into at least one other antenna (2) that, via the combination device (3), is connected to the second receiver (4') whose frequency is tuned to the test frequency. In order to conduct the self-test, the receiving levels of the second receiver (4') are recorded as actual values and compared with predetermined set values. This results in the realization of an antenna system in which a function check is conducted with the least possible amount of complexity.
