1. A device for testing a function of antennas, the device comprising:
a selection unit having inputs, an output, a first multiplexer with inputs and a second multiplexer with inputs;
an antenna system having a plurality of antennas, each one of said plurality of antennas being interconnected with a respective one of said inputs of said selection unit, wherein said antennas of a first antenna group of said plurality of antennas are interconnected with said inputs of said first multiplexer of said selection unit on a one-to-one basis, wherein said antennas of a second antenna group of said plurality of antennas are interconnected with said inputs of said second multiplexer of said selection unit on a one-to-one basis, and wherein said antennas of said first antenna group and said antennas of said second antenna group are disposed adjacently and/or so as to overlap in pairs;
a computing unit configured to:
provide control signals for said selection unit to feed an AC signal into a selected antenna of said first antenna group;
capture an antenna signal present on each of said antennas of said second antenna group for said selected antenna of said first antenna group at said output of said selection unit;
store the antenna signal for a subsequent evaluation; and
infer a fault in said selected antenna or the antenna system from a comparison of determined antenna signals for said selected antenna of said first antenna group and associated expected antenna signals.
