Abstract

The identification device in the form of a tag-like construction affixable to an object has at least one inductive element formed of flat conductor paths and a capacitive element formed from overlapping by overlaying conductor path parts and an interposed dielectric, which forms with the inductive element a closed resonant circuit, the conductor paths being arranged in at least two superimposed surfaces by folding together. In this way the conductor path parts forming the capacitive element are superimposed and they are at least partially identical with the conductor path parts forming the inductive element. In the method for the manufacture of the identification arrangement in the form of a tag-like construction affixable to an object, the conductor path constructions are arranged on an endless carrier path and the folding together of the conductor path construction is effected in that a continuously executed folding of the carrier path is carried out along a perforation line or fold-line.
