Patent ID: 8358246

Claim:
A stripline antenna-coupler for a RFID enabled system having a transceiver, the antenna-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 antenna-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; a first conductive strip being positioned at least partially between the first and second ground planes and configured to propagate a plurality of electromagnetic fields; and a second conductive strip being positioned at least partially between the first conductive strip and the second ground plane 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 the propagation of the plurality of electromagnetic fields from a side of each of the first and second conductive strips, the stripline antenna-coupler is configured to propagate the electromagnetic fields from the side of each of the first and second conductive strips in a direction generally parallel to the first and second ground planes for coupling with the targeted transponder in the transponder encoding region.
