RADIO FREQUENCY TRANSPONDER
(FR)
TRANSPONDEUR À RADIOFRÉQUENCES
Abstract:
(EN)
Information is encoded in a resonator/antenna structure, which may be interrogated in order to retrieve the information via radio frequency (RF) excitation. The resonator/antenna structure comprises a multiresonator including a plurality of substructures, and exhibits a plurality of resonances in the RF domain. Characteristic frequencies of the resonances depend upon the substructures, which may be modified in accordance with information to be encoded within the resonator/antenna structure. The resonator/antenna may be formed as a conductive structure disposed upon a dielectric substrate, and may be useful for encoding information within chipless RFID tags, security documents, negotiable instruments, and so forth. A variety of suitable multiresonator structures are disclosed, including multi-stop-band filters comprising cascaded spiral resonators, a "wheel and spoke" structure, an interleaved resonant circuit, and a fractal resonator structure.
(FR)
La présente invention concerne un transpondeur de radiofréquences. Les informations sont codées dans une structure de résonateur/antenne, qui peut être interrogée afin de récupérer les informations par excitation radiofréquence (RF). La structure de résonateur/antenne comprend un multirésonateur qui comprend une pluralité de sous-structures, et présente une pluralité de résonances dans le champ RF. Des fréquences caractéristiques des résonances dépendent des sous-structures, qui peuvent être modifiées conformément aux informations à coder dans la structure de résonateur/antenne. La structure de résonateur/antenne peut se présenter sous la forme d'une structure conductrice disposée sur un substrat diélectrique, et peut être utile pour coder des informations à l’intérieur d’étiquettes RFID sans puce, de documents de sécurité, d’instruments négociables, et ainsi de suite. Une variété de structures de multirésonateur appropriées est décrite, y compris des multifiltres éliminateurs de bandes qui comprennent des résonateurs hélicoïdaux en cascade, une structure « roue et rayons », un circuit résonant entrelacé, et une structure de résonateur fractale.
