A chip card having a card body having a metal layer that is at least partially covered by a coating that is more conductive than the metal layer, an RF chip, and a first RF antenna that is placed in a cut-out zone and connected to the chip. The metal layer includes at least one RF antenna portion that is electrically insulated from the metal layer and from the first RF antenna and that is configured to collect an image current induced by first eddy currents flowing at least over the coating of the metal layer and to allow coupling to the first antenna.
