AN ANTENNA FOR A COMMUNICATION TERMINAL

摘要

A radio antenna device for a radio communication terminal, e.g. a mobile telephone, comprising a flat ground plane and an antenna element having a radio signal feeding point disposed at the ground plane. The antenna element has a folded three dimensional box-like shape. The inventive antenna design provides for an antenna device with compact size, which at the same time is operable in UWB (Ultra Wideband) frequency regions. The antenna device may therefore advantageously be incorporated into a portable communication terminal such as a mobile telephone.
