a first radiating element formed as part of a component of an electronic device, said component comprising a conductive part and an electrically conductive mounting element for mounting the component on a substrate of the electronic device, wherein the conductive part forms the first radiating element and the mounting element is electrically connected to a feed line of the antenna and to a ground plane by a shunt line, the component having another operating function of the electronic device in addition to an antenna function, wherein the shunt line is provided on the substrate and operates as a second radiating element and wherein the shunt line is adapted to adjust the resonance frequency and provide impedance matching for the first radiating element.

2. An antenna assembly according claim 1 , wherein the component is a user control unit for controlling the operation of the electronic device.

3. An antenna assembly according to claim 1 wherein a transmission line is a further radiating element.

4. An antenna assembly according to claim 1 , wherein the conductive part forming the first radiating element forms a conductive frame supporting the component.

5. An antenna assembly according to claim 2 , wherein the component further comprises a second electrically conductive mounting element connected to a line receiving the control signal controlling the operation of the electronic device.

6. Antenna assembly according to claim 1 further comprising a third electrically conductive mounting element connected to a ground plane of the substrate.

7. Antenna assembly according to claim 1 further comprising a third electrically conductive mounting element connected to an open-circuited transmission line.

8. A network of antennas comprising at least two antenna assemblies according to claim 1 .

9. A dual-band antenna, comprising two antenna assemblies according to claim 1 .

10. A user control unit for operating an electronic device, the user control unit comprising an antenna assembly having a first radiating element formed as part of a component of an electronic device, said component comprising a conductive part and an electrically conductive mounting element for mounting the component on a substrate of the electronic device, wherein the conductive part forms the first radiating element and the mounting element is electrically connected to a feed line of the antenna and to a ground plane by a shunt line, the component having another operating function of the electronic device in addition to an antenna function, wherein the shunt line is provided on the substrate and operates as a second radiating element and wherein the shunt line is adapted to adjust the resonance frequency and provide impedance matching for the first radiating element: wherein the component is a control element for operating a function of the electronic device and the conductive part is a conductive support frame for supporting the control element.

11. An electronic communication device comprising at least one antenna assembly according to claim 1 .

12. An electronic communication device comprising a user control unit for operating the electronic device, the electronic device comprising housing for receiving the electronic communication device; a substrate for supporting one or more electronic components of the electronic device; and the user control unit comprising at least one control element for operating a function of the electronic device; a conductive support frame for supporting the control element and provided with a plurality of mounting elements for mounting on the substrate; wherein the conductive support frame forms a first radiating element of an antenna for wireless applications of the electronic device and one of the mounting elements is electrically connected to a feed line to feed the antenna and shunted to ground by means of a shunt line, wherein the shunt line is provided on the substrate and operates as a second radiating element and wherein the shunt line is adapted to adjust the resonance frequency and provide impedance matching for the first radiating element.
