  • Publication number: 20070024423
    Abstract: A radio frequency identification system comprises a radio-frequency identification substrate and an interrogator. In one embodiment, the radio-frequency identification substrate comprises a plurality of radio-frequency identification devices. In one embodiment, a controller on the substrate controls a first one of the plurality of radio-frequency identification devices based on a state of a second one of the plurality of radio-frequency identification devices. In one embodiment, an antenna system includes an S-shaped portion electrically coupled to an integrated circuit along a central portion of the S-shaped portion. Adjusting the parameters of the segments making up the S-shaped portion controls performance characteristics of a radio-frequency identification device.

  • Publication number: 20070001778
    Abstract: A system useful in providing communications with automatic data collection (ADC) devices employs an antenna located in a potentially hazardous environment, a radio circuit located in a non-hazardous environment, and a coupling apparatus to provide an interface between the antenna and the radio circuit that prevents electrical discharges from occurring in the potentially hazardous environment.

  • Publication number: 20060232413
    Abstract: A radio frequency identification (RFID) tag includes an antenna having a shape providing a machine-readable or human-readable code or symbol. For example, a machine-readable code may comprise a bar code, or other suitable optical code. Human-readable symbols may include, for example, text, alpha-numeric symbols, icons, or pictographs. Using human-readable antenna forms, an RFID tag may be used as a label, for example, to add a distinctive look to the tagged product, to further identify the tag or product it is attached to, or for branding the tag or attached product.

  • Publication number: 20060220869
    Abstract: An RF transponder comprises a transponder integrated circuit, an antenna connected to the transponder integrated circuit, and at least one parasitic element adapted to interact electrically with the antenna and thereby affect antenna impedance. The orientation of the parasitic element with respect to the antenna is selected to achieve a desired operational frequency band for the RF transponder. Specifically, the spacing between the antenna and the parasitic element is selected to achieve the desired operational frequency band. For example, a first selected spacing may enable an operational frequency band suitable for a first geographic region (e.g., the United States), a second selected spacing may enable an operational frequency band suitable for a second geographic region (e.g., Europe), and a third selected spacing may enable an operational frequency band suitable for a third geographic region (e.g., Japan).

  • Publication number: 20060000915
    Abstract: An RFID tag may include an antenna substrate comprising a conductive layer etched or deposited to form an antenna, and a circuit substrate comprising a conductive layer etched or deposited to form a circuit, the antenna electro-magnetically coupled to the circuit. An RFID tag may be formed from an insert substrate comprising an insulative layer between two conductive layers, one of the conductive layers etched to form an antenna and the other conductive layer etched to form a circuit. The insert substrate may be received in an envelope formed by a label substrate, which may carry a pressure sensitive adhesive.
