Abstract

The disclosure relates to an antenna device for a radio communications apparatus operating in dual frequency bands and being switchable between a stand-by position and a talk position. In the antenna device, there are included two antenna elements (11, 12) for the stand-by position and two antenna elements (15, 16) for the talk position. The two pairs of antenna elements (11, 12; 15, 16) both include an antenna element for each frequency band. The antenna elements for the stand-by position consist of two helix antennae, where the one is disposed within the other, and the antenna elements for the talk position constitute a rod arrangement (3) which is displaceable through the helix antennae arrangement (4). The helix antennae (11, 12) are galvanically separated from one another. The antenna elements (15, 16) of the rod arrangement (3) are disposed axially in sequence after one another and galvanically discrete from one another.
