Title (EN) REACTIVELY COUPLED ELEMENTS IN CIRCUITS ON FLEXIBLE SUBSTRATES
(FR) ELEMENTS COUPLES DE MANIERE REACTIVE DANS DES CIRCUITS SUR SUBSTRATS SOUPLES
Abstract:
(EN) An RFID circuit for incorporation in an identification device which includes a polymeric substrate (12), the circuit being formed or integrally connected with said substrate whereby the substrate becomes a component of the RFID circuit. An embodiment of the circuit includes circuit elements (10, 14) printed or attached to opposite sides of the substrate utilizing the resistance of the substrate in a reactive or inductive circuit.
(FR) Cette invention se rapporte à un circuit à identification radio (RFID) conçu pour être incorporé à un dispositif d'identification qui comporte un substrat polymère (12), ledit circuit étant formé avec ou intégralement relié audit substrat, ce qui transforme le substrat en un composant du circuit RFID. Une réalisation de ce circuit comporte des éléments de circuit (10, 14) imprimés ou fixés sur les côtés opposés dudit substrat, qui utilisent la résistance dudit substrat dans un circuit réactif ou inductif.
