Abstract
An antennae device for reading electronic labels includes passive antennae arranged in the form of an array comprising L lines and C columns. The antennae are located in the array by co-ordinates (i, j), i ranging from 1 to L, j ranging from 1 to C. Each antenna (i, j) is controlled by two control switches, one controlling the antennae located on a line i, the other controlling the antennae located on a column j.
