INSERT FORMING AN ANTENNA AND SMART CARD COMPRISING SAME

摘要

The invention relates to an insert forming an antenna (20) for a smart card, comprising: an antenna-forming central layer (21) comprising a substrate (22) and at least one conductor (24) extending along at least one surface of the substrate (22); at least one covering layer (30) covering at least one side of the central layer (21) and capable of compensating for the surface irregularities of the surface of the central layer (21). The covering layer(s) (30) comprise a proximal sheet (32) located close to the central layer (21) and a distal sheet (34) located away from the central layer (21), the two sheets being stacked and laminated and the proximal sheet (32) has, during the lamination phase, a lower fluidity than that of the distal sheet (34).
