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.

Storage cabinet with improved RFID antenna system

In accordance with a preferred embodiment of the invention, an antenna structure is provided having one or more antennae arranged so as to read all possible orientations of a randomly placed tag. Also provided in accordance with a preferred embodiment of the invention, is a method of configuring one or more antennae composed of the steps of: identifying the 'dead zones' of each discrete antennae used, and orienting each antennae such that there are no 'dead zones' common to all antennae. The unique antenna structure (and corresponding method) has particular application in tag reader antenna systems for use in RFID (radio frequency identification) applications (13.56 MHz) and the like. In accordance with an exemplary embodiment, multiple RF (radio frequency) antennae are utilized as part of an intelligent station to track items tagged with radio frequency identification (RFID) tags.

Apparatus for and method of using a diversity antenna

An RFID reader system for tracking and locating RFID tags is described, along with an antenna suitable for use in this system, and an antenna configuration apparatus for use in this system. The system offers an antenna configuration that is cost-effective and easily reconfigurable, in which antennas with integral tuning components can be moved or replaced with antennas of a similar or different format. An end user is therefore able to easily reconfigure his or her platform in the field, in order to account for different products or different product orientations. Specific orientations of the reader antennae will furthermore increase system functionality by permitting multiple tag locations on the product.
