Patent ID: 8669915

Claim:
An apparatus comprising: at least one frame component comprising 1/xth of a 360 degree radio frequency identification (RFID) tag reader antenna array, wherein the frame component is configured to physically couple to at least one other of the frame components to form a multi-frame component; at least one RFID tag reader antenna mount comprising a part of the frame component, wherein the RFID tag reader antenna mount is configured to aim a corresponding RFID tag reader antenna outwardly of the frame component; a first group of the plurality of RFID tag reader antennas disposed at a first substantially-identical pitch and a second group of the plurality of RFID tag reader antennas are disposed at a second substantially-identical pitch, wherein the first substantially-identical pitch and the second substantially-identical pitch are different from one another; such that connecting X of the frame components together will yield the 360 degree RFID tag reader antenna array having a plurality of RFID tag reader antennas disposed thereon and wherein the plurality of RFID tag reader antennas comprise a first group of the plurality of RFID tag reader antennas that are disposed at a first substantially-identical pitch and a second group of the plurality of RFID tag reader antennas that are disposed at a second substantially-identical pitch, wherein the first substantially-identical pitch and the second substantially-identical pitch are different from one another.
