Electronic antenna module optimised for a chip card with a dual communication interface

Electronic module for a smart card, comprising a substrate having on a first face a terminal block of electrical contacts standardized according to ISO 7816 allowing operation by contact with the corresponding contacts of a smart card reader, and comprising on a second face an antenna and a microelectronic chip protected by an encapsulation zone and provided with a contact communication and a contactless communication interface, the electrical contacts being connected to the chip by conductive wires passing through connection wells, the antenna comprising a plurality of turns located on the periphery of the module and a proximal connection pad and a distal connection pad arranged inside the encapsulation zone and intended to be connected to corresponding terminals of said contactless communication interface of the chip, and the turns of the antenna comprising a localized recess bypassing the distal connection pad and oriented towards the chip, wherein the distal connection pad is located at a small distance d from the edge of the encapsulation zone, and wherein the internal edges of the connection wells of the two contacts closest to the distal connection pad are spread outwards from the module with respect to the internal edges of the connection wells of the other contacts, so as to maximize the space available between the distal connection pad and said connection wells for the passage of the antenna tracks.
