Title (EN) COUPLING ANTENNA WITH HIGH INDUCTANCE
(FR) ANTENNE DE COUPLAGE A INDUCTANCE ELEVEE
Abstract:
(EN) The invention concerns a coupling antenna consisting of a plurality of turns in series located on a planar support (14) formed by an insulating dielectric substrate. Said antenna comprises one or several sets of at least one turn (16) located on said planar support, mounted in series, at least one of the sets consisting of at least two spires (16, 22) in series superposed along an axis perpendicular to the plane of said support and separated by an insulating strip (20) of dielectric ink, thereby resulting in a high inductance value. The invention also concerns the method for making such an antenna and the use of said antenna in a contactless smart card.
(FR) L'invention concerne une antenne de couplage constituée par une pluralité de spires en série situées sur un support plan (14) constitué par un substrat diélectrique isolant. Cette antenne comprend un ou plusieurs ensembles d'au moins une spire (16) située sur ledit support plan, montés en série, au moins un des ensembles étant constitué par au moins deux spires (16, 22) en série superposées selon un axe perpendiculaire au plan dudit support et séparées par une bande isolante (20) d'encre diélectrique, ce qui permet d'obtenir une valeur d'inductance importante. L'invention concerne également le procédé de fabrication d'une telle antenne et l'utilisation de cette antenne dans une carte à puce sans contact.
