Abstract:
(EN) Methods of forming electronic signal transmitting/receiving devices and electronic signal transmitting/receiving devices are described. In one implementation, integrated circuitry including transponder circuitry is provided and operatively coupled with an antenna to provide a transmitting/receiving circuit. A matrix material comprising suspension structure is formed and applied over at least a portion of the antenna, the suspension structure being selected to manipulate an operating characteristic of the transmitting/receiving circuit. According to a preferred aspect of the invention, the operating characteristic comprises an electrical length of the antenna and the application of the matrix material effectively increases the electrical length to resonate the antenna at a desired frequency. According to another preferred aspect of the invention, the suspension structure comprises calcium carbonate.
(FR) Procédés permettant de former des dispositifs électroniques d'émission/réception de signaux et dispositifs ainsi produits. Dans un mode de réalisation, un circuit intégré comportant un circuit transpondeur est couplé de manière opérationnelle à une antenne pour produire un circuit émetteur/récepteur. Un matériau matrice comportant une structure de suspension est formé et appliqué sur au moins une partie de l'antenne, la structure de suspension étant sélectionnée pour manipuler une caractéristique de fonctionnement du circuit émetteur/récepteur. Selon un aspect préféré de la présente invention, la caractéristique de fonctionnement comporte une longueur électrique de l'antenne et l'application du matériau matrice augmente la longueur électrique de manière à faire résonner l'antenne à une fréquence désirée. Selon un autre aspect préféré de la présente invention, la structure de suspension comporte du carbonate de calcium.
