The present invention is directed to a living-being proximity sensing arrangement for a vehicle. The arrangement is arranged for distinguishing proximity of a human or animal body from proximity of a non-living object, and comprises a sensor unit including an antenna array, wherein the antenna array is operable in a plurality of operational modes for enabling use of said antenna array for performing at least one of a plurality of different electrical sensing techniques in each of said modes. The antenna array comprises means for providing an antenna input signal to said antenna array and means for presenting an antenna output signal from said antenna array, a plurality of patches spanning a first detection area of the antenna, and a plurality of interconnections between said patches. These interconnections are switchable for enabling connection and disconnection of said switchable electrical connections between said patches for enabling operation of said antenna in each of said plurality of operational modes.
