Abstract
(EN)
This antenna device (101) comprises: a first feeding coil (31) connected to a feeding circuit; a second feeding coil (32) connected to the feeding circuit; a first resonance circuit including a first current path formed of a conductor pattern, which is magnetically coupled to the first feeding coil (31); and a second resonance circuit including a second current path formed of a conductor pattern, which is magnetically coupled to the second feeding coil (32). The resonance frequency of the first resonance circuit and the resonance frequency of the second resonance circuit are equal to the extent that the frequency characteristics of the impedance magnitudes of the first resonance circuit and the second resonance circuit viewed from the power feeding circuit are unimodal.

L’invention concerne un dispositif d'antenne (101) qui comprend : une première bobine d'alimentation (31) connectée à un circuit d'alimentation ; une seconde bobine d'alimentation (32) connectée au circuit d'alimentation ; un premier circuit de résonance comprenant un premier trajet de courant formé d'un motif conducteur, qui est couplé magnétiquement à la première bobine d'alimentation (31); et un second circuit de résonance comprenant un second trajet de courant formé d'un motif conducteur, qui est couplé magnétiquement à la seconde bobine d'alimentation (32). La fréquence de résonance du premier circuit de résonance et la fréquence de résonance du second circuit de résonance sont égales dans la mesure où les caractéristiques de fréquence des amplitudes d'impédance du premier circuit de résonance et du second circuit de résonance vues depuis le circuit d'alimentation électrique sont unimodales.
