Novel laser anti-counterfeiting ultrahigh-frequency RFID tag antenna and production process thereof

Abstract

The present invention discloses a novel laser anti-counterfeiting ultrahigh-frequency RFID tag antenna. The antenna comprises a PET base material, laser coatings are arranged on the upper end surfaceand the lower end surface of the PET base material, and an aluminum foil layer is arranged on the surface of the laser coating at the upper end of the PET base material. The novel laser anti-counterfeiting ultrahigh-frequency RFID tag antenna is technically characterized in that: 1, the laser coatings of which the physical properties meet the requirements of a production process are selected; 2, an impression plate roller with unique anti-counterfeiting identification degree is manufactured; and 3, a hot stamping transfer process is controlled. The novel laser anti-counterfeiting ultrahigh-frequency RFID tag antenna adopted by the invention has the following main advantages: the laser anti-counterfeiting antenna realizes the self anti-counterfeiting and tracing functions of the tag antenna; and the laser hot stamping process is combined with the process requirements of the PET base material, so that the production difficulty is increased, and imitation is completely eradicated.

Description

technical field [0001] The invention belongs to the technical field of RFID tag antennas, and in particular relates to a novel laser anti-counterfeit ultra-high frequency RFID tag antenna and a production process thereof. Background technique [0002] At present, the conventional antenna design adopted by the RFID label industry is to use colorless transparent PET film as the main substrate of the antenna, and aluminum foil is glued to the colorless transparent PET film by glue, and then the antenna is made by printing, etching and other processes. [0003] The main disadvantages of this process: 1. Due to the chip encryption technology, the RFID tag itself can play the function of anti-counterfeiting and traceability, but as a component antenna of the label, it has not been able to achieve anti-counterfeiting; 2. In terms of anti-counterfeiting and identification of conventional antennas At present, all manufacturers use the same factory emblem or logo as the antenna patter...

Problems solved by technology

[0003] The main disadvantages of this process: 1. Due to the chip encryption technology, the RFID tag itself can play the function of anti-counterfeiting and traceability, but as a component antenna of the label, it has not been able to achieve anti-counterfeiting; 2. In terms of anti-counterfeiting and identification of conventional antennas At present, all manufacturers use the factory emblem or logo consistent with the antenna pattern design for anti-counterfeiting and traceability. This method has no real anti-counterfeiting and traceability functions.
