Patent ID: 7893881

Claim:
An antenna device for a portable radio communication device operable in at least a first and a second frequency band, the antenna device comprising: a first electrically conductive radiating element having a feeding portion connectable to a feed device (RF) of the radio communication device; a second electrically conductive radiating element having a grounding portion connectable to ground; a controllable switch connected between the first and second radiating elements for selectively interconnecting and disconnecting the first and second radiating elements, the state of the switch being controlled by means of a control voltage input (V switch ); a first filter connected between the feeding portion and the control voltage input (V switch ), wherein the first filter is arranged to block radio frequency signals; a high pass filter connected between said first and second radiating elements, which high pass filter provides an RF bridge between the first and second radiating elements and thereby allows RF signals to pass, so that the first and second radiating elements are operable as one single radiating element.
