Chip card with optimized coupling antennas and method for the production thereof

Abstract

Example embodiments relate to chip cards with optimized coupling antennas and methods for the production thereof. An example contactless or mixed contact and contactless chip card includes a chip card body and an antenna insert interposed between outer layers of the chip card body. The antenna insert includes a substrate. The antenna insert also includes on at least one side of the substrate, coils of a concentrator configured to be electromagnetically coupled to coils of an antenna of an electronic module arranged in a cavity of the chip card body. The concentrator includes at least one inner coil that emerges in the cavity and is flush with inner side walls of the cavity of the chip card body.
