Hand-held transmitting and/or receiving apparatus
First Claim
1. A hand-held radio transceiver comprising:
- a housing having a top end and a bottom end, and front and rear sides extending between the top and bottom ends;
an earphone disposed on the housing front side adjacent the top end thereof;
an antenna system extending along the housing rear side and having a ground plane disposed generally opposite the earphone, a resonant element extending along a resonator plane generally parallel to the ground plane, and a feeder element, the resonant element having a grounding end spaced away from the housing top end and a free edge extending from said grounding end toward the housing top end, and a ground connector extending between and electrically connecting the ground plane to the resonant element grounding end, the feeder element electrically connecting the resonant element to an electric circuit without mechanically contacting the resonant element;
said electric circuit being within the housing and electrically connected to the antenna system via an elastic, electrically conductive element positioned between said electric circuit and said feeder element forming an electrical connection therebetween;
the housing of said transceiver terminating short of a region opposite to said resonant element free edge along the direction of said resonant plane, whereby signals tend to radiate from the resonant element upwardly and away from the earphone.

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.
