Abstract
Abstract A resonance label (1) comprises an insulating support layer (4) having two sides (2, 3). A first conductor is on one side (3) of the insulating supporting layer (4) and forms a capacitor plate (6b) and an induction coil (5) having a number of individual turns spaced apart from each other. A second conductor is on the other side (2) of the insulating supporting layer (4) and forms another capacitor plate (6a) so as to define a resonant circuit. At least one of the first and second conductors includes two adjacent conductor areas (6a, 7d) which are spaced apart at a distance (a) from each other closer to one another than the spacing between the individual turns of the induction coil (5). The distance (a) between the adjacent conductor areas (6a, 7d) defines a desired breakdown point (8) on the respective side (2) of the insulating support layer (4).
