Abstract
A portable electronic device comprises an antenna ANT connected to an integrated circuit CI, allowing the establishment by the integrated circuit of near-field contactless communications with an external system. The antenna comprises several windings EElinked together by current-conducting means. Each winding has its ends connected to connection terminals of a circuit. The antenna then comprises, at the minimum, a winding Econnected to the terminals for connection to the integrated circuit CI able to establish contactless communications with an external system, and a winding Econnected to the terminals for connection to a peripheral component CP, which can comprise one or more circuits connected in series, and which is powered remotely by the antenna.
