Abstract

A slot antenna (21) is arranged to be connected to an asymmetrical output (29) of an antenna circuit (25). The antenna comprises a dielectric substrate (23), and a printed circuit conducting element (22; 22') attached to the substrate and defining a radiating slot (24; 24') of the antenna and having parallel edges. The antenna is characterized in that it further comprises a printed central line (27; 27') arranged in the slot (24; 2440 ) and allowing the direct connection of the output (29) in such a manner that this central line (27; 27') realizes the transition between the output and the antenna.
