Abstract: A system having a multi-coupler array is provided. Each coupler is configured to communicate with a targeted transponder from among a group of multiple adjacent transponders. The couplers may each include one or more conductive strips, at least one terminating load, a dielectric material, a first ground plane, and a second ground plane. Each of the conductive strips can extend between the first and second ground planes and the dielectric material from an input end connected to a transceiver to a loaded end connected to the terminating load. The conductive strips may be configured to propagate electromagnetic fields concentrated in a near field region of the conductive strips in a direction generally perpendicular to the conductive strips to couple with a targeted transponder. The coupler may include an enclosure for directing the electromagnetic fields. The conductive strip may have a tapered or non-linear profile such as a modified bow-tie profile.
