Abstract

The device has a printed-circuit board (5), on one side of which at least one antenna (1) is located and, on the other side of which electrical circuits (3) are located. An electromagnetic shield between the antenna (1) and the electrical circuits (3) is realized in a manner that is simple with regard for production engineering by locating a feeder network (13, 15)—developed using a coplanar circuit technique and with which the at least one antenna (1) is contacted—on the antenna-side surface of the printed-circuit board (5), and by covering the antenna-side surface of the printed-circuit board (5) with the connected-to-ground outer conductor (45) of the coplanar circuit to such an extent that the required shield between the antenna (1) and the electrical circuits (3) is produced as a result.
