    Abstract: A RFID system and an associated antenna-coupler are provided. The system may be for selectively communicating with a targeted transponder from among a group of multiple adjacent transponders is provided. The system may include a transponder conveyance, a transceiver, and an antenna-coupler. The transponder conveyance is adapted to transport at least one targeted transponder from a group of multiple adjacent transponders through a transponder operating region. The transceiver is configured to generate one or more electrical signals. The antenna-coupler has first and second microstrips in a cross-like arrangement relative to each other. Each of the first and second microstrips is configured to transmit one or more electro-magnetic fields concentrated in a near-field region of the antenna-coupler based on the one or more electrical signals for communicating with the targeted transponder.

    Abstract: An RFID system for selectively communicating with a targeted transponder from among a group of multiple adjacent transponders is provided. The RFID system may include a transponder conveyance system adapted to transport at least one targeted transponder from a group of multiple adjacent transponders through a transponder encoding area along a feeding direction and an antenna having a resonant inductor and a ferrite material, wherein the ferrite material at least partially covers the resonant inductor and defines an exposed portion of the resonant inductor. In one antenna-transponder alignment, the exposed portion extends substantially parallel to the feeding direction.

    Abstract: A near-field coupling device that may facilitate communications with a transponder is provided. The near-field coupling device may include a ground plane, a dielectric substrate, one or more conductive strips and a terminating load. The conductive strips together with the ground planes form coupling elements. The near-field coupling device further includes one or more switching elements for selectively connecting and disconnecting the coupling elements with a transceiver. The connected coupling elements define a total characteristic impedance. Using the switching element, the ratio between the total characteristic impedance of the connected coupling elements and the terminating load may be changed in order to adjust the distribution of an electromagnetic field along the coupling elements according to the type and position of the transponder to be processed.
