  • RFID tag, antenna, and printer system
    Patent number: 7261479
    Abstract: An RFID label with embedded tag is passed through an RFID antenna in a printer system, where the RFID antenna allows a roll of such labels to pass in close proximity to the antenna and still allow each individual RFID tag to be read and/or programmed. The RFID antenna module is formed with a transmission line coupled to an RF phase splitter, where in one embodiment, the transmission line is formed from two parallel conductive strips.
    Type: Grant
    Filed: February 7, 2006
    Date of Patent: August 28, 2007
    Assignee: Printronix
    Inventors: Gordon B. Barrus, Richard E. Schumaker, Andrew W. Edwards, Kevin Mark Smith, Duane C. Gibbs, Rudy Concepcion, Jr.

  • RFID tag, antenna, and printer system
    Patent number: 6929412
    Abstract: An RFID label with embedded tag is passed through an RFID antenna in a printer system, where the RFID antenna allows a roll of such labels to pass in close proximity to the antenna and still allow each individual RFID tag to be read and/or programmed. The RFID antenna is formed with two parallel microstrip transmission lines coupled to an RF phase splitter there between.
