Abstract: Exemplary embodiments are disclosed of antenna devices for portable radio communication devices. In an exemplary embodiment, there is an antenna device for a portable radio communication device adapted for receiving radio signals in at least one frequency band. The antenna device includes a radiating element having a first branch and a second branch connected to a common elongated feeding section.

Abstract: Exemplary embodiments are disclosed of antenna devices for portable radio communication devices. In an exemplary embodiment, an antenna device comprises a monopole radiating element to be positioned along one end of a portable radio communication device, for operation of a plurality of complementary frequency bands including the FM frequency band. A feed offset positioned on the monopole radiating element divides the monopole radiating element in a first part and a second part to provide at least one complementary frequency band additional to the FM frequency band. The FM frequency band and the at least one additional complementary frequency band are fed through the feed.

Abstract: An exemplary embodiment includes a multiple-turn loop antenna arrangement comprising a multiple-turn loop element. The multiple-turn loop element is arranged in a first layer. A ground plane element is arranged in a second layer. The first and second layers are arranged in parallel. The multiple-turn loop element is arranged on top of the ground plane element. The ground plane element comprises slots interrupting eddy currents in the ground plane element, which would short signals in the multiple-turn loop element.

Abstract: Exemplary embodiments are disclosed of antenna arrangements for portable radio communication devices. In an exemplary embodiment, there is an antenna arrangement for a portable communication device having a metal casing. A front side part forms a ground plane means for the portable radio communication device. A first back side part is connected to the front side part through a top side part. A second back side part is connected to the front side part through a bottom side part. The top and bottom side parts are positioned at opposite ends of the front side part. The first and second back side parts are positioned and distanced from each other by a gap. A magnetic type antenna element is positioned partly in the gap and positioned partly over or along the first back side part, the top side part, or the front side part.
