Methods, systems, and apparatuses for radio frequency identification (RFID) items/objects are described. In embodiments of the present invention, resonant frequency characteristics of materials of the items/objects are used to enable RFID functionality in the items/objects. In an aspect of the present invention, a RFID item comprises a resonant material. An integrated circuit (IC) die is electrically coupled to the resonant material. The resonant material functions as an antenna for the IC die. The IC die may be attached to a quadraposer substrate to be electrically coupled to the resonant material.

L'invention concerne des procédés, des systèmes et des appareils destinés à des articles/objets d'identification de radiofréquences (RFID). Dans des modes de réalisation, des courbes de résonance de matériels des articles/objets sont utilisés pour activer une fonctionnalité RFID dans les articles/objets. Dans un aspect de l'invention, un article RFID comprend un matériel résonant. Un dé à circuit intégré (CI) est couplé électriquement au matériel résonant. Le matériel résonant fonctionne comme une antenne pour le dé CI. Le dé CI peut être fixé à un substrat quadripolaire pour se coupler électriquement au matériel résonant.
