Claim:
1. An apparatus for operating at least two separately disposed and independent near-field communications (NFC) antennas of a motor vehicle, the apparatus comprising: a switching device to be coupled to the at least two separately disposed and independent NFC antennas and configured to perform a switching process and to use the switching process to change a respective input capacitance of one antenna of the at least two antennas; a multiplexing device connected to said switching device, said multiplexing device being configured to select one of the at least two antennas for near field communication and to connect the selected antenna to an output; and said multiplexing device and said switching device being configured, when changing over from a first antenna having a first input capacitance to a second antenna having a second input capacitance, to match the second input capacitance to the first input capacitance by performing the switching process.
