Ultrathin wave-absorbing material anti-metal electronic label

Abstract

The invention relates to an ultrathin wave-absorbing material anti-metal electronic label, specifically relates to an ultrathin anti-metal label, and belongs to the technical field of an electronic label. The ultrathin absorbing material anti-metal electronic label comprises a chip, an aluminum etching antenna and a wave-absorbing material, wherein the chip is connected with the aluminum etching antenna, and the aluminum etching antenna and the wave-absorbing material are in attached connection through a glue layer; the frequency range of the chip is 13.5 6MH or 860MHz-960MHz; and the thickness of the wave-absorbing material is 0.15-0.35mm. The electronic label and the wave-absorbing material are bendable and are directly applied to the surface of bent metal or embedded in the metal for application, the thickness dimension is ultrathin, the performance is excellent, and the ultrathin wave-absorbing material anti-metal electronic label is applied to such industrial fields as miniaturized product tracing, industrial and fire-fighting gas cylinder whole-course tracing, miniature asset management, component maintenance management and the like.

Description

technical field [0001] The invention relates to an ultra-thin wave-absorbing material anti-metal electronic tag, in particular to an ultra-thin anti-metal tag, which belongs to the technical field of electronic tags. Background technique [0002] When the RFID electronic tag is read on the metal surface, the electromagnetic field emitted by the reader causes an eddy current effect inside the metal. On the one hand, it weakens the electromagnetic field energy emitted by the reader. On the contrary, the magnetic force lines on the metal surface are relatively flat, which makes the electronic tag unable to effectively cut the magnetic field lines to obtain energy, so that the reading and writing distance is greatly reduced, and even cannot be read. [0003] At present, the conventional solution is to increase the distance between the antenna and the metal surface, that is, to place a layer of non-metallic material, such as PVC, PET, PP, etc., between the antenna layer of the el...
