Reconfigurable and replaceable RFID antenna network
First Claim
1. A system for tracking and locating RFID tags, comprising:
- a reader unit;
a switch matrix including single pole multiple throw switches;
a plurality of reconfigurable and replaceable antennae;
a controller for communicating with the reader and for controlling a state of the switch matrix,wherein the reconfigurable and replaceable antennae are located at multiple points that are at least one of within and on at least one shelf;
wherein the RFID tags are attached to items located on the at least one shelf, andwherein the reader unit uses the reconfigurable and replaceable antennae to communicate with the RFID tags; and
a base joined with the at least one shelf, the base defining a plurality of slots, wherein the antennae are replaceably and reconfigurably plugged into selected slots, wherein other slots remain unoccupied by said antennae.

Abstract
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.
