ABSTRACT:
A system for tracking RFID tags with a reader device having a plurality of antennas. The antennas are positioned such that portions of at least two of the plurality of antennas physically overlap each other and are in approximately the same plane. A pair of overlapping antennas are also positioned so that an RFID tag is positioned within both signal fields of the pair of overlapping antennas. In addition, the reader device is configured to selectively activate the plurality of overlapping antennas to thereby selectively interrogate one or more of the RFID tags, and the reader device is configured to use the selective interrogation of the one or more RFID tags to track the locations of the RFID tags.
