An arrangement for wirelessly coupling a radio device, in particular a mobile telephone, via a radio link, in particular to a device of a motor vehicle or to a stationary radio device, wherein - the arrangement has a contact surface for placing the radio device thereon, - the arrangement has an antenna in order to produce and maintain the wireless coupling of the radio device, or has a plurality of antennas positioned side by side which can be selectively operated in order to produce and maintain the wireless coupling of the radio device, - the contact surface has a rotationally symmetrical recess extending around an axis of rotation perpendicular to the contact surface such that, at different rotational positions relative to the axis of rotation, a radio device having a projection which engages in the recess can operate a radio link to the antenna, or to one antenna of the plurality of antennas, and such that alternatively a radio device which does not engage in the recess but rests against the contact surface can be located in any orientation and any position within a space delimited by the contact surface and the arrangement and can operate a respective radio link to the antenna, or to one antenna of the plurality of antennas, - the arrangement comprises a charging coil on a primary side for generating an electromagnetic field which can be received by a charging unit of the radio device on a secondary side and can be used for charging an energy storage of the radio device, - the charging coil on the primary side is oriented relative to the axis of rotation such that the magnetic flux density of the electromagnetic field generated by the charging coil on the primary side is at a maximum in the direction of the axis of rotation characterized in that - the antenna or the antennas is/are in each case formed by at least one electrically conductive layer that is borne by a substrate made of electrically non-conductive material, wherein the layer(s) extends/extend along the contact surface, and, - the electrically conductive layer(s) of at least a part of the antennas is/are disposed with respect to the contact surface at a distance less than or equal to that of the charging coil. - the arrangement has a contact surface for placing the radio device thereon, - the arrangement has an antenna in order to produce and maintain the wireless coupling of the radio device, or has a plurality of antennas positioned side by side which can be selectively operated in order to produce and maintain the wireless coupling of the radio device, - the contact surface has a rotationally symmetrical recess extending around an axis of rotation perpendicular to the contact surface such that, at different rotational positions relative to the axis of rotation, a radio device having a projection which engages in the recess can operate a radio link to the antenna, or to one antenna of the plurality of antennas, and such that alternatively a radio device which does not engage in the recess but rests against the contact surface can be located in any orientation and any position within a space delimited by the contact surface and the arrangement and can operate a respective radio link to the antenna, or to one antenna of the plurality of antennas, - the arrangement comprises a charging coil on a primary side for generating an electromagnetic field which can be received by a charging unit of the radio device on a secondary side and can be used for charging an energy storage of the radio device, - the charging coil on the primary side is oriented relative to the axis of rotation such that the magnetic flux density of the electromagnetic field generated by the charging coil on the primary side is at a maximum in the direction of the axis of rotation - the antenna or the antennas is/are in each case formed by at least one electrically conductive layer that is borne by a substrate made of electrically non-conductive material, wherein the layer(s) extends/extend along the contact surface, and, - the electrically conductive layer(s) of at least a part of the antennas is/are disposed with respect to the contact surface at a distance less than or equal to that of the charging coil.
