STORAGE CABINET WITH IMPROVED RFID ANTENNA SYSTEM
First Claim
1. An antenna assembly for use with a reader to detect a plurality of RFID tags comprising:
- a first antenna being closed so as to have a first perimeter and extending along a first axis; and
a second antenna extending along the first axis, the first antenna located within the first perimeter and the second antenna being proximal to the first antenna, the second antenna being of a type such that it is isolated from the first antenna.

Abstract
A system for reading RFID tags of articles within a cabinet includes a repositionable shelf. The repositionable shelf includes an antenna assembly having three antenna pairs. Each antenna pair has a loop antenna and a figure eight antenna. The antenna pairs are on a PC board. The PC board includes an RJ45 connector which provides both power to the antenna assembly as well as a communication interface for the antenna assembly. The RJ45 connector could be used to provide the RF signals from the antenna to a reader. The system could also include a repositionable divider for placement perpendicular to the repositionable shelf. The repositionable divider also includes a loop antenna and a figure eight antenna.
