Abstract

L'invention concerne un système d'identification radiofréquence (RFID) comprennent un lecteur et une étiquette. Le lecteur RFID comprend au moins une antenne de lecteur. L'antenne de lecteur est conçue comme antenne cadre avec perte et comporte une zone de couverture de faisceau. L'étiquette RFID comprend une antenne cadre, l'antenne cadre d'étiquette coopérant avec l'antenne de lecteur pour recevoir et transmettre des signaux radiofréquences entre l'antenne de lecteur et l'antenne d'étiquette lorsque l'étiquette est située avec une distance de champ proche de l'antenne de lecteur.
