Abstract

Detection tag for a resonance de-tection system, comprising a support consisting of electrically insulating ma-terial and a resonant circuit supported thereby. The resonant circuit consists of an inductive element formed by a con-ductor track disposed on the support in a predefined pattern and of a capacitive element formed by at least two capacitor electrodes which are kept apart by the support and are constructed as electro-conductive electrodes regions. The ends of the track are connected to the one and to the other capacitor electrode, respec-tively. At least one electroconductive is-land region (6) is disposed on the support (1) so as to be adjacent to, and in the same plane as, one of the capacitor elec-trodes (7). The edges of the island re-gion (6) and the capacitor electrode (7), which face one another, are situated at such a distance from one another that a discharge gap is delimited therebetween.
