Abstract:
The invention relates to a contactless chip card intended to communicate with a chip card reader operating at a resonant frequency F 0 ′. The chip card includes a booster antenna provided with an inductive main antenna U and with an inductive concentrator antenna L 2 , which antennae are connected in series or parallel with a capacitor C, wherein the inductances of L 1  and L 2  and the capacitance of C are chosen on the one hand to obtain a resonant frequency F 0  that is far enough from the frequency of the signal emitted by the reader to limit radiofrequency communication with the reader, and on the other hand so that the connection in parallel of a predetermined capacitance C d  brings the resonant frequency of the card into the vicinity of said frequency F 0′  of the signal emitted by said reader.

Claim (Index 1):
A chip card with contactless operation, configured to communicate with a chip card reader operating at a resonant frequency F 0 \u2032, said chip card being provided with a card body incorporating at least one antenna connected in series or in parallel with a capacitor, wherein inductances of the antennae and the capacitance of the capacitor have values that achieve a resonant frequency F 0  remote enough from the frequency of a signal emitted by the reader to limit radiofrequency communication with the reader, such that the chip card is detuned by default with respect to the reader, and the values of said inductances and capacitor furthermore being such that the connection, in parallel, of a predetermined additional capacitance C d  brings the resonant frequency of the card close to the frequency F 0 \u2032 of the signal emitted by said reader, such that the chip card is retuned with the reader, wherein the chip card includes a booster antenna provided with a main antenna with inductance L 1  and with a concentrator antenna with inductance L 2  that are connected in series or in parallel with a capacitor C, and wherein the values of L 1 , L 2  and C are chosen firstly so as to achieve said resonant frequency F 0  and secondly so that the connection, in parallel, of said predetermined capacitance C d  brings the resonant frequency of the card close to said frequency F 0 \u2032 of the signal emitted by said reader.
