Abstract (en)

The present invention relates to an antenna device for a portable radio communication device adapted for receiving and/or transmitting radio signals in at least a first and a second operating frequency band. The antenna device comprise a half-loop radiating element (2), comprising a first end and a second end, configured for receiving FM frequencies, wherein the antenna device comprises a band stop filter (6) and a capacitor (4) at the first end and an inductor (5) at said second end, the half-loop radiating element (2) is configured to also operate at DVB-H frequencies, the band stop filter (6) is arranged to block the DVB-H frequencies to provide an open-ended termination of the half-loop radiating element (2) for DVB-H frequencies, and the inductor (5) is arranged to short circuit the half-loop radiating element (2) to ground for FM frequencies.
