Abstract
The invention concerns a transmission/reception antenna comprising a ground plane and at least a planar radiating surface extending plumb over said ground plane and parallel thereto. The invention is characterised in that the radiation section(s) are linked to means defining at least an adaptation circuit which, in transmission as well as in reception is resonant on simultaneously at least two frequency bands.
Claims10
A transmission/reception antenna comprising a ground plane and at least one planar radiation surface which extends plumb with said ground plane and parallel thereto, characterized in that the radiation section or sections are linked to means defining at least one matching circuit which, both in transmission and in reception, is simultaneously resonant on at least two frequency bands.
The antenna as claimed in one of the preceding claims, characterized in that it comprises at least two radiation surfaces linked by means forming at least one matching circuit.
A portable telephone, characterized in that it comprises an antenna as claimed in one of the preceding claims.
