An antenna for a Radio-Frequency IDentification (RFID) system is disclosed that comprises a resonant structure, an RFID load element, and a floating coupling element. One of the two terminals of the RFID load element is connected directly to the resonant structure, and the other terminal is connected to the floating coupling element. The floating coupling element is electrically isolated from the resonant structure, and its presence allows for an improved impedance match to the RFID load element.
L'invention porte sur une antenne pour système d'identification radiofréquence (RFID) qui comprend une structure résonante, un élément de charge RFID et un élément de couplage flottant. L'une des deux bornes de l'élément de charge RFID est connectée directement à la structure résonante, et l'autre borne est connectée à l'élément de couplage flottant. L'élément de couplage flottant est électriquement isolé de la structure résonante, et sa présence permet une adaptation d'impédance améliorée à l'élément de charge RFID.
