    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 security tag for use with an electronic security system which functions within a second frequency range comprises a substantially planar dielectric substrate having first and second sides. A first conductive pattern is provided on the first side of the substrate, the first conductive pattern comprising at least a first inductive element, a first plate of a first capacitive element and a first plate of a second capacitive element. A second conductive pattern located on the second side of the substrate comprises at least a second inductive element, a second plate of the first capacitive element and a second plate of a second capacitive element with the plates of the capacitive elements being generally aligned. The inductive elements and the capacitive elements form a resonant circuit which resonates at a first frequency within a first frequency range which is outside of the second frequency range. A direct electrical connection extends through the substrate to electrically connect the first conductive pattern to the second conductive pattern to thereby continuously maintain both sides of the substrate at substantially same static charge level.
