Portable radiotelephone
First Claim
1. A mobile radiotelephone comprising a casing, a printed circuit card placed inside the casing, and an antenna constituted by a radiating conductive element and by a ground plane, the radiotelephone being characterized in that:
- said radiating conductive element is disposed outside said casing, is mechanically connected thereto, and extends substantially parallel to said printed circuit card;
said printed circuit card has means forming a ground plane;
the distance h between said radiating conductive element and said printed circuit card lies in the range 7 mm to 15 mm; and
said radiating conductive element is disposed inside an insulating piece that is mechanically connected to said casing and that presents sufficient mechanical strength to constitute a fastener system for said radiotelephone.

Abstract
The invention provides a mobile radiotelephone comprising a casing, a printed circuit card placed inside the casing (30), and an antenna constituted by a radiating conductive element (44) and by a ground plane (50). The radiotelephone is characterized in that the radiating conductive element (44) is disposed outside the casing (30), is mechanically connected thereto, and extends substantially parallel to the printed circuit card. The printed circuit card (42) carries means forming a ground plane (50). The distance h between the radiating conductive element (44) and the printed circuit card (42) lies in the range 7 mm to 15 mm. The radiating conductive element is embedded in an insulating piece (44) mechanically connected to the housing and presenting sufficient mechanical strength to constitute a fastener system for the radiotelephone.
