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.
