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 ( ) extending between first and second opposite edges ( ), and a feed portion. The conductive structure ( ) is formed to a radiating structure ( ) partially enclosing a volume, and the first and second edges ( ) are located at a distance from each other forming a radiating first slit ( ), 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.
