ANTENNA, APPARATUS AND METHOD FOR IDENTIFYING AND TRACKING MULTIPLE ITEMS
First Claim
1. A flat identification antenna for receiving signals from a tag attached to an item placed on the antenna, the antenna comprising an antenna core, the antenna core comprising:
- a first planar array comprising a plurality of first discrete planar loops made of conductive material, said plurality of first loops are arranged so as to partially overlap each other in a first direction;
a second planar array parallel to said first planar array, the second array comprising a plurality of second discrete planar loops made of conductive material, said plurality of second loops are arranged so as to partially overlap each other in a second direction different from the first direction; and
an insulating board positioned between said first and second arrays.

Abstract
A flat identification antenna for receiving signals from multiple tag-carrying items placed on the antenna and a system for identifying and tracking multiple tag-carrying items including the same. The antenna comprises a first planar array of partially overlapping first planar loops, a second planar array of partially overlapping second planar loops and an insulating board positioned between the first and second arrays. The loops in the first array are arranged to partially overlap each other in one direction and the loops in the second array are arranged to partially overlap each other in another direction.
