Abstract
Disclosed is a device (D') for near-field radiofrequency communication with a portable element, the device including: at least one near-field communication primary antenna (A) having a predetermined communication frequency (Fc); and a microcontroller (′) electrically connected to the primary antenna, including a power supply source for the primary antenna and a receiver unit for the data (′) received by the primary antenna. The communication device further includes: at least one passive relay antenna (A. . . A), juxtaposed with the primary antenna, relay frequencies (F. . . F), lying within a range of values around the predetermined communication frequency (Fc), but different from the predetermined communication frequency (Fc), electrically connected to the data receiver unit. Also included is a unit (C) for adjusting the relay frequency. The communication device can be used to enlarge the near-field communication surface of the communication device.
