Abstract
The antenna-forming insert for a chip card includes a central layer forming an antenna including a substrate and at least one conductor extending along at least one face of the substrate. At least one cover layer covering on at least one side the central layer and capable of compensating for the irregularities of the surface of the central layer. Each cover layer includes a proximal sheet located in proximity to the central layer and a distal sheet located away from the central layer, both sheets being superposed and laminated and the proximal sheet during the lamination phase has lower fluidity than that of the distal sheet.
