Portabel elektronisk kommunikationsanordning med dubbelbandigt antennsystem

摘要

A portable electronic communication device, such as a mobile telephone, has first and second housing elements, which are movable relative to each other, and an antenna system for electromagnetic communication within a first and a second frequency band. The antenna system is made by a printed conductive pattern, which is arranged on or in the second housing element and is connected to element for radio communication inside the first housing element. The printed pattern includes an antenna portion and an impedance matching portion for allowing the antenna portion to operate at frequencies within said first and second frequency bands.
