Hand-held transmitting and/or receiving apparatus
First Claim
1. A hand-held radio transceiver comprising:
- a housing,an electric circuit comprising a substrate positioned within the housing and supporting electric circuit components thereon,a conductive covering separate from said housing, having first and second sides, a first side positioned over said substrate and enclosing said electric circuit components,an antenna system extending along the housing adjacent to said electric circuit, comprising a ground plane, wherein said conductive covering forms said ground plane, said antenna system further comprisinga resonant element extending generally parallel to the ground plane, the resonant element having a free end, said resonant element extending on said second side of said conductive covering forming said ground plane and opposite to said electric circuit, anda ground connector extending between and electrically connecting the ground plane to the resonant element at a grounded location distal from said free end.

Abstract
Hand-held transmitting and/or receiving apparatus, including a housing made of electrically non-conductive material, an electric circuit positioned within the housing, an electrical ground plane positioned within the housing, an antenna resonator 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 an arrangement for connecting the ground plane and the resonator element to the electric circuit. The resonator element, the ground plane and the ground connector are positioned about and fixed to a dielectric body positioned inside the housing. This antenna is easily manufactured and reduces the influence of mechanical tolerances and mechanical and thermal influences on the electrical parameters of the antenna.
