Zusammenfassung:	Improved antenna for contactless chip card The invention relates to an antenna for contactless chip card making it possible to communicate with a chip card reader with the aid of a carrier signal of frequency F0modulated by a data signal of frequency f, characterized in that it is configured to present at the same time, for a given bitrate of communication between the chip card and the reader, at least three resonance peaks (P1,P2,P3), namely a first peak (P2) close to the frequency of the carrier F0, and at least 2nlateral peaks (P1,P3) close to the data transmission frequencies Fo +. n.f and F0- n.f, where n represents the number of harmonics of the signal to be transmitted.
