Abstract
An antenna device for transmitting and/or receiving RF waves connectable to a radio communication device and including a radiating structure with at least two switchable antenna elements. At least one switching element, arranged in a central switching unit, selectively connects and disconnects the at least two switchable antenna elements. The at least two antenna elements can be individually switched between different coupling states by the central switching unit. The central switching unit has a control port for reception of control signals enabling the central switching unit to effect a centralized switching of said at least two switchable antenna elements.
