Abstract

Un dispositif pourvu une antenne de communication en champ proche en quadrature est proposé. Le dispositif comprend : un boîtier; une première antenne NFC (communication en champ proche) comprenant une bobine environ parallèle à un côté donné du boîtier conçue pour produire un premier champ magnétique qui sétend du côté donné du boîtier; une seconde antenne NFC environ parallèle à la première antenne NFC, la seconde antenne NFC comprenant au moins une bobine respective formant deux boucles de courant opposé conçues pour produire un second champ magnétique perpendiculaire au premier champ magnétique; et un circuit pour faire fonctionner la première antenne NFC et la seconde antenne NFC en phase en quadrature.
