Abstract: A monopole type antenna suitable for operating in cellular frequency bands, the antenna comprising: a conductive surface forming a radiating element and including an electrical connection zone; a compact conductive counterpoise including a connection zone; and a feed line comprising an antenna cable connected to the connection zones of said radiating element and of said compact counterpoise. In the antenna, said radiating element is in the form of an open loop having two branches both connected to the antenna cable and defining first and second radiating portions, each of the radiating portions is suitable for entering into resonance at at least one cellular frequency and extends in a main direction; and these two main directions are substantially parallel so as to operate parasitically and with coupling between the two radiating portions.

Abstract: The invention relates to a patch type antenna comprising:

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.

Abstract: The invention relates to an antenna of colinear type.

Abstract: The invention provides an elongate antenna.
