La présente invention concerne une étiquette d'identification par radiofréquence (RFID) qui comprend un circuit RFID et une antenne formée à partir d'éléments distincts d'indices visuels. L'antenne peut fonctionner sensiblement comme une antenne dipôle avec une première partie du logo fonctionnant comme un élément conducteur de l'antenne et une seconde partie du logo fonctionnant comme un second élément conducteur de l'antenne. Les lettres et les formes dans les indices peuvent être couplées électriquement à des connecteurs électriques réduits visuellement au minimum. Les bornes du circuit RFID sont connectées à chaque partie du logo. Le circuit RFID peut être disposé dans un espace non conducteur entre deux moitiés d'une lettre ou d'une forme commune, et une couche supérieure peut être disposée sur l'espace pour sceller électriquement l'espace et relier visuellement les deux moitiés de la lettre ou de la forme commune.
