Patent ID: 7586410

Claim:
A stripline coupler for a RFID enabled system having a transceiver, the coupler being adapted to couple a transceiver with a targeted transponder in a transponder encoding region from among a group of multiple adjacent transponders, the coupler comprising: a first ground plane and a second ground plane spaced apart from each other; at least one connection between the first ground plane and the second ground plane for connecting the first ground plane to the second ground plane; and a conductive strip being positioned at least partially between the first and second ground planes and configured to propagate a plurality of electromagnetic fields; wherein the first ground plane, the second ground plane, and the at least one connection promote propagation of the plurality of electromagnetic fields from a side of the conductive strip; and wherein the propagation of the plurality of electromagnetic fields from the side of the conductive strip is in a direction generally perpendicular to a length of the conductive strip and generally parallel to the first and second ground planes for coupling with the targeted transponder in the transponder encoding region.
