Abstract
A hand-held transmitting and/or receiving apparatus includes an elongated housing, an electric circuit inside the housing, an earphone positioned at one end of the front side of the housing, an electric ground plane positioned on the rear side of the housing at an end opposite the earphone, an antenna resonant element extending approximately parallel to the ground plane and having a first free end and a second end electrically connected by a ground connector to the ground plane, and a device connecting the ground plane and resonant element to the electric circuit. The free end of the resonant element points towards the end of the housing at which the earphone is positioned. In this arrange the strength of the electrical field of the antenna is lowest near hand or the head of the user. This reduces health risks and influences due to the hand or the body of the user on the electric field of the antenna.
