Abstract
The invention relates to a ground arrangement of a device using wireless data transfer. In order to improve the electric properties of the device and to minimize the SAR value of the device, at least one electrically conductive additional ground lead () is formed in the device in addition to the actual ground lead (). In between the ground lead and the additional ground lead, a galvanic coupling is automatically established, when a predetermined switching criterion is fulfilled, and the aforementioned galvanic coupling is automatically released, when a predetermined release criterion is fulfilled. This enables one to change the ground configuration of an antenna such that it is as suitable as possible for the transmission and reception circumstances each time existing.
