Abstract:
1. An electronic device comprising at least one integrated circuit and a planar antenna connected to the integrated circuit so as to establish a near-field contactless communication with an external system, the device furthermore comprising at least one peripheral component connected to the antenna, allowing it to be remotely powered, wherein the antenna comprises: a. a first inductive winding, comprising one or more loops, one end of which starts from a first terminal for connection to the integrated circuit and another end of which arrives at a second terminal for connection to the integrated circuit, and further having at least one connection point near one of the first and second terminals; b. a second inductive winding, comprising one or more loops, one end of which starts from a first terminal for connection to the peripheral component and another end of which arrives at the second terminal for connection to the peripheral component; and c. a conductive link (wire) between the at least one connection point of the first inductive winding and the at least one connection point of the second inductive winding, such that the windings are linked by current-conducting means.
