The invention relates to an antenna for a contactless smart card, arranged on an insert intended to be integrated in said smart card having a certain relative vertical or horizontal positioning tolerance T between the insert and the body of the card, said smart card being provided with an embossing area comprising lines of characters embossed in relief, at least one antenna coil being situated opposite the embossing area, wherein said coil comprises at least one pair of paths situated in the embossing area and connected in parallel, said paths being configured in such a way that at least one of same remains at least partially situated outside of the embossed character area whatever the relative position of the insert and the antenna of same allowed by the tolerance T.

Contactless smart card comprising an antenna optimized to allow embossing of characters

A contactless chip card intended to communicate with a chip card reader operating at a first resonant frequency includes a booster antenna provided with an inductive main antenna and with an inductive concentrator antenna, which antennae are connected in series or parallel with a capacitor. The inductances of the inductive main antenna and the inductive concentrator antenna and the capacitance of the capacitor are chosen on the one hand to obtain a second resonant frequency 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 brings the resonant frequency of the card into the vicinity of said first resonant frequency of the signal emitted by said reader.
