Memory card of the contactless type
First Claim
1. A memory card (C) comprising a card body (1) of plastics material having an integrated circuit (3) embedded in one face (2) thereof, with a coupling antenna (4) on said face being connected to two contact pads (6) of the integrated circuit (3), and organized as a spiral pattern, wherein turns of the spiral pattern pass over a flush face (5) of the integrated circuit (3), and an insulating protective sheet (7) covering said face of the card body, wherein the antenna (4) is constituted by a conductive track, wherein a width of the conductive track is locally decreased in a zone (10) of the face (2) of the card body directly surrounding the integrated circuit (3) to connection with conductive lines (4.3) that are narrow compared with the conductive track outside said zone and organized on the flush face (5) of the integrated circuit (3) and passing between the two contact pads (6) of said integrated circuit.
