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