A device according to claimcharacterised in that the interrupting zone is positioned outside the switch zone in which two wires () of a circuit are so arranged as to cooperate with the switch are positioned.

Method for producing radiofrequency communication devices with or without operation switch and devices thus obtained

The invention relates to a portable electronic device comprising a supporting member receiving on one side conductive contact lands or tracks extending substantially as far as the edge of the side and connecting an electronic microcircuit, the conductive contact lands or tracks comprising a plurality of perforations. The device is noteworthy in that the interior of the perforations is free, or intended to be kept free, of metal.

Portable device with apertured electrical contacts

The invention relates to a radio frequency device including an antenna connected to a capacitor. Said capacitor includes first and second conductive plates that are opposite each other and separated by an insulator. At least one of said first and second plates is formed of a plurality of wire capacitor portions. Said radio frequency device is different in that the antenna and at least one capacitor plate are formed with wire portions placed on a substrate in a guided manner.

Wire capacitor, in particular for a radio frequency circuit, and device comprising said wire capacitor

The invention relates to a radiofrequency device comprising a passive antenna tuned or intended to be tuned in frequency with at least one transponder, said transponder comprising an integrated circuit chip linked to an antenna interface defining an electromagnetic coupling surface periphery, said passive antenna comprising a main loop formed of turns comprising at least one portion of surface (B) inside the loop, at least one recess of the main loop, oriented from the interior to the exterior of the main loop, said portion of surface (B) being located in said recess so as to effect an electromagnetic coupling with a transponder circuit; the device is distinguished in that it comprises two recesses receiving or intended to receive a transponder each.
