    摘要： The present invention relates to a security element for electronic article surveillance, comprising two at least partially overlapping layers of conductor strips interconnected by a dielectric adhesive coating. This arrangement reduces the risk of reactivation after activation is once effected. To achieve this, the upper layer and the lower layer of conductor strips have at least one turn, and that the strength of the two layers of overlapping conductor strips is so high as to cause the security element to bend, if subjected to mechanical strain, in those areas which are essentially devoid of conductor strips.

    摘要： The present invention relates to a security element for electronic article surveillance, having one lower and one upper conducting track with at least one winding each, the two conducting tracks being wound in opposing directions and overlapping in at least one area of overlap, and a dielectric layer in the area of overlap between the two conducting tracks. In a critical area in which a border edge of the lower and upper conducting tracks overlap, the dielectric layer is thicker than in the remaining area of overlap. The present invention also relates to a method of manufacturing such a security element.

    摘要： An electronic anti-theft element consists of at least one spiral printed circuit, a capacitor and a dielectric layer arranged therebetween, or of two spiral printed circuits which are arranged on respective sides of a dielectric layer in an at least partially overlapping manner (forming resonant circuit). The object of the invention is to provide a resonant circuit which is less liable to be reactivated. For that purpose, in at least one selected area (a rated break point) of the dielectric layer a short-circuit is created between the opposite capacitor plates or spiral printed circuits when a sufficiently high energy is supplied by a magnetic alternating field. The selected area is locally reinforced, preventing the suppression of the short-circuit by mechanical stress and the reactivation of the anti-theft element.

    摘要： A resonant circuit for an anti-theft element consists of two spiral printed circuits and one dielectric layer. The spiral printed circuits are wound in opposing directions and arranged on opposite sides of the dielectric layer so that they at least partly overlap. At least one selected area is provided in which a conductive path arises between the two spiral printed circuits whenever a sufficiently high energy is applied by means of an external alternating field.
