Abstract
A portable electronic communication device, such as a mobile telephone, has first and second housing elements, which are moveable relative to each other, and an antenna system for electromagnetic communication within at least two different frequency bands. The antenna system is made by a printed pattern of an electrically conductive material, which is arranged on the second housing element and is connected to elements for radio communication inside the first housing element. A first portion of the printed pattern resonates at a frequency within a first frequency band, and a second portion of the printed pattern resonates at a frequency within a second frequency band.
