Abstract

L'invention concerne donc une antenne de couplage connectée à un dispositif d'émission/réception d'ondes électromagnétiques contenant un ou plusieurs condensateurs intégrés. Cette antenne de couplage comprend au moins une spire (24) sérigraphiée sur un support (28) constitué par un substrat diélectrique isolant et comprend également un condensateur sérigraphié sur le support, connecté en parallèle, permettant ainsi de réduire la capacité
fournie par le(s) condensateur(s) intégré(s) dans le dispositif, pour que la capacité résultante forme un circuit résonant avec la spire.
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 ou hybride contact - sans contact.
