Media rolls, support structures for the media rolls, and media processing systems are provided. A media roll may include an identification transponder having retrievable information regarding the media units and associated media unit transponders wound around a core of the media roll. A support structure may include a spindle for supporting a media roll and include an identification coupler for communicating with the identification transponder. In addition to the spindle having the identification coupler, the media processing systems may include a second coupler for encoding the media unit transponders and a printhead for printing indicia onto the media units. The information retrieved from the identification transponder may be used to adjust one or more encoding and/or printing settings of the systems.

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 electromagnetic 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.
摘要:
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.

摘要:
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.
