Claim 10:
11. A method for testing a function of an antenna system having a plurality of antennas that are each interconnected with a respective input of a selection unit, wherein the antennas of a first antenna group of the plurality of antennas are interconnected with inputs of a first multiplexer of the selection unit on a one-to-one basis, wherein the antennas of a second antenna group of the plurality of antennas are interconnected with inputs of a second multiplexer of the selection unit on a one-to-one basis, and wherein the antennas of the first antenna group and the antennas of the second antenna group are disposed adjacently and/or so as to overlap in pairs, the method which comprises the steps of:
providing a computing unit which performs the substeps of:
providing control signals for the selection unit to feed an AC signal into a selected antenna of the first antenna group;
capturing an antenna signal present on each of the antennas of the second antenna group for the selected antenna of the first antenna group at an output of the selection unit and stores the antenna signal for a subsequent evaluation; and
inferring a fault in the selected antenna or the antenna system from a comparison of determined antenna signals for the selected antenna of the first antenna system and associated expected antenna signals.
