    摘要: A security tag used with an electronic article surveillance system for detecting the presence of the tag within a surveilled area utilizing electromagnetic energy at a frequency within a predetermined detection frequency range includes a dielectric substrate having first and second opposing principle surfaces, a peripheral outer edge, and a resonant circuit capable of resonating at a frequency within the predetermined detection frequency range. The security tag also includes a guard member, in one embodiment a discontinuous conductive member, effectively electrically isolated from the resonant circuit, extending along at least a portion of the peripheral outer edge of the substrate for surrounding at least a portion of the resonant circuit. The guard member electrically isolates the resonant circuit to facilitate testing of the resonant circuit during an early stage of the manufacturing process when the resonant circuit is in web form.

    摘要: A capacitor strap that is applied to a security tag coil or antenna to form and properly tune an EAS or an RFID security tag. The capacitor strap is a thin film capacitor formed of two metal foils in between which is a dielectric material having ends that are electrically coupled to different points of a security tag coil or antenna. The capacitor strap may include an RFID integrated circuit, either in series or in parallel with the capacitor, which is then applied to security tag coil at a particular location to tune the tag to a predetermined frequency.

    摘要: A communication-ready corrugated article and method for making the corrugated article is disclosed. The corrugated article includes a linersheet (e.g., craft paper), an undulating medium (e.g., craft paper), a conductive strip (e.g., metal, aluminum, wire, coil), and a security chip (e.g., RFID chip, EAS chip, integrated circuit, chip strap, RFID tag, EAS tag). The linersheet has a first side and a second side. The undulating medium is coupled to the first side of the linersheet, the conductive strip is positioned on the first side of the linersheet between the linersheet and the undulating medium. The security chip is attached to the second side of the linersheet opposite the conductive strip and is coupled to the conductive strip through the linersheet.
