The disclosure relates to an antenna device for a portable radiocommunications apparatus, for example a so-called cell or mobile telephone, which has at least one but preferably several operating frequencies within one frequency range. The frequency range has a width of several times the lower limit frequency of the frequency range, for example 800-2200 MHz. The antenna device has a radiating structure in the form of a continuous conductor. At least a first and a second section of the conductor are connectable to and disconnectable from each other. The interconnection takes place by the intermediary of connecting devices that are controlled by a control unit. |
