Abstract
An antenna means for transmitting and/or receiving RF signals, a radio communication system and a method for manufacturing a radiating structure. The antenna means comprises a conductive structure (10) extending between first and second opposite edges (11, 12), and a feed portion. The conductive structure (10) is formed to a radiating structure (1) partially enclosing a volume, and the first and second edges (11, 12) are located at a distance from each other forming a radiating first slit (21), which has a first and a second open end. Hereby an antenna means, which can be made compact, and can operate in more than one frequency band is obtained. A second slit can be arranged to improve the operation in a higher frequency band. The radio communication system comprises transmitting/receiving circuits connected to an such antenna means.
