The present disclosure relates to an arrangement and a method for detecting the approach of an object and the teachings thereof may be embodied in a system for providing passive keyless vehicle access. A device may include: a communication device with an antenna to generate an electromagnetic field at regular intervals in a polling mode; and a processor to determine at least one operating parameter of the antenna whenever an electromagnetic field is generated, to compare the at least one determined operating parameter with a corresponding previously determined operating parameter, wherein a change in the at least one operating parameter indicates that an object is approaching the device, and to emit a signal if the comparison reveals that an operating parameter has changed.
