Detection tag
First Claim
1. A detection tag for a resonance detection system, comprising a support consisting of electrically insulating material and a resonant circuit supported thereby, which has an inductive element formed by a conductor track disposed on the support in a predefined pattern, and a capacitive element formed by at least two capacitor electrodes which are kept apart by the support and are constructed as electroconductive electrode regions, the ends of the track being connected to the one and to the other capacitor electrode, respectively, wherein at least one island region (13) is disposed on a first side of the support (1) so as to be adjacent to, and in the same plane as, the conductor track (4) and so as to be separated from a second side of the support, in that one end of the island region is connected to one end of the track, and in that there is present, between the edges thereof facing each other, a discharge gap (12).

Abstract
A detection tag for a resonance detection system. A resonance circuit is supported on an electrically insulative support, and includes and inductive track in a predefined pattern and a capacitive element with capacitor electrodes separated from each other by the support and connected to the respective ends of the inductive track. An electroconductive island is provided on the first side of the support with one of the capacitor electrodes, and is separated from that capacitor electrode by a discharge gap distance, and is also separated from the capacitor electrode on the other side of the support.
