Patent number: 7650114Abstract: A system having a UHF RFID transceiver is adapted to communicate exclusively with a single electro-magnetically coupled transponder located in a predetermined confined transponder operating region. The system includes a near field coupling device comprising a plurality of lines connected in parallel with an unmatched load. The near field coupling device may be formed, for example on a printed circuit board with a plurality of electrically interconnected traces and a ground plane. The system establishes, at predetermined transceiver power levels, a mutual electro-magnetic coupling which is selective exclusively for a single transponder located in a defined transponder operating region. Also included are methods for selective communication with the transponder in an apparatus such as a printer-encoder.Type: GrantFiled: June 5, 2008Date of Patent: January 19, 2010Assignee: ZIH Corp.Inventors: Boris Y.

Patent number: 7586410Abstract: A stripline coupler for a RFID system is provided. The coupler is configured to communicate with a targeted transponder from among a group of multiple adjacent transponders. The coupler may include a conductive strip, a terminating load, a dielectric material, a first ground plane, and a second ground plane.

Publication number: 20080238606Abstract: A near-field coupler for a RFID system is provided. The coupler is configured to selectively communicate with a targeted transponder from among a group of multiple adjacent transponders. The coupler includes a conductive strip terminated by a load. The load is for matching an input impedance of the coupler to a source impedance of a transceiver. The conductive strip is based on a quarter wavelength of the center operating frequency. The conductive strip may have a substantially constant width and a length substantially equal to the quarter wavelength. Or the conductive strip may have a variable width defining a tapered profile and a length less than the quarter wavelength. The tapered profile may be an exponential profile or a Klopfenstein profile. Due to the overall size of the coupler to a typical transponder, the center of the coupler and the center of the transponder may be offset during coupling.Type: ApplicationFiled: March 30, 2007Publication date: October 2, 2008Inventors: Boris Y.

Patent number: 7425887Abstract: A RFID coupler capable of selectively communicating with a targeted transponder from among a group of multiple adjacent transponders. The coupler includes a grounded terminal load, a coupling element, a connecting element, an impedance matching element, and an input terminal. The coupling element is connected with the grounded terminal load and is configured to couple with the transponder by emanating an electromagnetic field. The input terminal is connected to a transceiver for receiving communication signals. The impedance matching element is connected to the input terminal and is configured to substantially match an input impedance of the coupler to a source impedance of the transceiver. The connecting element connects the impedance matching element to the coupling element. The coupling element and the impedance matching element are substantially parallel and separated by at least one dielectric layer and at least one ground plane.Type: GrantFiled: September 21, 2005Date of Patent: September 16, 2008Assignee: ZIH CorporationInventors: Boris Y.
