Abstract: 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.

Abstract: An insert for a chip card includes a body provided with a cavity in which is inserted an electronic module provided with a microelectronic chip connected to an inductive or capacitive coupling. The body has a stack of layers at least a first layer of which comprises a first booster antenna and a second layer of which comprises a second booster antenna, the various booster antennas being coupled together inductively and/or capacitively, and at least one of the booster antennas being coupled inductively and/or capacitively with the coupling of the module. The body furthermore comprises at least one metal plate disposed between two layers of ferrite, the first and second booster antennae and the metallic plate being arranged in such a way that at least one of the two booster antennas and the electronic module remain coupled together inductively and/or capacitively, despite the presence of the metal plate.
