Abstract

L'invention concerne une antenne pour carte à puce sans contact permettant de communiquer avec un lecteur de carte à puce à l'aide d'un signal porteur de fréquence F0 modulé par un signal de données de fréquences f01, f02, comportant un premier circuit résonnant (L1,C1) présentant un pic de résonnance de fréquence foi et un second circuit résonnant (L2,C2) présentant un pic de résonnance de fréquence f02 , caractérisée en ce que les deux circuits résonnants ne sont pas électriquement connectés entre eux et sont couplés électro magnétiquement entre eux par un facteur de couplage K faible, inférieur à 20 %.The invention relates to an antenna for a contactless chip card making it possible to communicate with a chip card reader using a carrier signal of frequency F0 modulated by a data signal of frequencies f01, f02, comprising a first circuit resonant circuit (L1, C1) having a resonance peak of frequency f02 and a second resonant circuit (L2, C2) having a resonance peak of frequency f02 , characterized in that the two resonant circuits are not electrically connected to each other and are electromagnetically coupled together by a low coupling factor K, less than 20%.
