Abstract: A security tag for use with an electronic article surveillance system comprises a flexible, substantially planar dielectric substrate having first and second sides. A first conductive pattern is positioned on the first side of the substrate, and a second conductive pattern is positioned on the second side of the substrate. The first and second conductive patterns cooperate to establish a resonant circuit, including at least one inductive element and at least one capacitive element having first and second generally separated plates. A static dissipation member, such as a frangible connection member, is provided for electrically connecting together the first and second plates of the at least one capacitive element for preventing the at least one capacitive element from charging and short circuiting to thereby provide electrostatic discharge protection for the security tag. In one embodiment, the frangible connection is formed by a conductive frame member positioned on the substrate and extending around at least a portion of the second conductive pattern.
