An antenna means (2) for transmitting and receiving RF signals, comprising: a ground plane (11) arranged to be connected to ground of the circuitry of a radio communication device and a conductive radiating structure (20) in the form of a band. The radiating structure has in a first end a feed portion (21) arranged to be coupled to circuitry of a radio communication device. The radiating structure has a second end which is a free end (29). The band has a first (A) and a second (B) surface, and is divided by bent portions into a number of sections Sn along its length. The band is bent or folded so that the first surface (A) of a first section S1 faces the first surface (A) of a second section S2, being adjacent to the first section S1, and the second surface (B) of a section Sm faces the second surface (B) of a consecutive section Sm+1, whereby a compact antenna means which can operate within a wide frequency band is achieved.
