PROCEDE DE CONNEXION SUR UNE SEULE ANTENNE D'UN OU DE PLUSIEURS COMPOSANTS SANS CONTACT, ET SYSTEME CORRESPONDANT

摘要

The system (SYS) has an impedance matching circuit (CAI) defining a configuration in which a resonant circuit is formed using a component (CMP1) and an inductive antenna (ANT), and another configuration in which another resonant circuit is formed using the component, another component (CMP2) and the antenna, where the resonant circuits respectively include two resonant frequencies compatible with carrier frequency. A controller (MG) respectively sets the matching circuit in the two configurations in absence and presence of the latter component cooperating with an interface (INT). An independent claim is also included for a method for coupling an antenna with components exchanging information with an external device via the antenna.
