Abstract

L'invention concerne un système d'antennes RFID amélioré destiné à un système d'identification d'articles, ce système d'antennes RFID présentant les caractéristiques suivantes : les au moins deux antennes à plaque (21) forment un groupe d'antennes à plaque (A, B) pour concentrer et ainsi resserrer la zone de surveillance dans la direction de passage (3') et les au moins deux antennes à plaque (21) sont disposées à égale distance d'une surface de base (5) de la voie de passage (3) et/ou sur le même plan horizontal ou de façon décalée de telle sorte qu'une droite passant par les centres et/ou les centres de gravité d'au moins deux antennes à plaque (21) voisines forme avec un plan horizontal et/ou un plan parallèle à la surface de base (5) un angle α inférieur ou égal à 45°.
