The electronic device () comprising a microcircuit () module (), a near-field communication antenna () electrically connected to the microcircuit () of the module (), delimiting an antenna surface (S), and a body () incorporating the module (). More precisely, the antenna () is arranged within the module () and the body () incorporates means () of amplifying the gain of the antenna () comprising an electrically conductive element () electrically isolated from the microcircuit () and the antenna (), of an annular general shape arranged around an area (R) of the body () forming a volume generated by the projection of the antenna surface (S) along a direction (Z) substantially orthogonal to the surface (S).

Microcircuit device including means for amplifying the gain of an antenna

This circuit () comprises a first antenna () connected to the microcircuit () and capable of supplying power to the microcircuit () by electromagnetic coupling with an external terminal and a second antenna () electromagnetically coupled to the first antenna () while remaining electrically isolated from the latter. In addition, the first () and second () antennas consist respectively of first and second windings having opposite winding directions as defined from the same observation point.

Microcircuit device including a near-field communication antenna circuit

The electronic module () for an electronic device () such as a microcircuit card, comprises a substrate () delimiting first (A) and second (B) opposite faces. More particularly, the module () comprises a light source () borne by the second face (B) of the substrate () and capable of illuminating a visible part of the electronic device.
