Novel double-frequency fragile RFID tag antenna and production method thereof

Abstract

The invention discloses a novel double-frequency fragile RFID tag antenna. The antenna comprises a first aluminum foil layer, a fragile coating, a PET layer and a second aluminum foil layer. The fragile coating is coated on the surface of the upper end of the PET layer through composite glue. The first aluminum foil layer is arranged at the upper end of the fragile coating through composite glue.The first aluminum foil layer is arranged at the upper end of the PET layer through composite glue, the second aluminum foil layer is arranged at the lower end of the PET layer through composite glue,double-frequency antennas are printed and etched on the first aluminum foil layer and the second aluminum foil layer, each double-frequency antenna comprises a high-frequency part and an ultrahigh-frequency part, and the high-frequency parts in the double-frequency antennas are riveted and conducted to form a high-frequency antenna loop. According to the invention, while a dual-frequency range data reading function is realized, secondary utilization is avoided due to self-destruction of fragile characteristics, and the functions of substantial anti-counterfeiting and tracing are realized. Andthe production difficulty is increased, and imitation is avoided. Data protection of the product by a user is facilitated, imitation products and counterfeit products circulated in the market are reduced, and benign competition of industrial production is improved.

Description

technical field [0001] The invention belongs to the technical field of RFID tag antennas, and in particular relates to a novel dual-frequency fragile RFID tag antenna and a production method thereof. Background technique [0002] At present, the conventional design of the dual-frequency antenna used in the RFID industry is to use colorless transparent PET film as the main base material of the antenna, and the aluminum foil is bonded 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: [0004] 1. The RFID dual-frequency antenna can realize the reading of information data in the two frequency bands of high frequency and ultra-high frequency. It is precisely because of its own dual-frequency band reading design that it brings convenience to management, and at the same time, it also causes a double problem of information reading leakage. risk.

Problems solved by technology

[0004] 1. The RFID dual-frequency antenna can realize the reading of information data in the two frequency bands of high frequency and ultra-high frequency. It is precisely because of its own dual-frequency band reading design that it brings convenience to management, and at the same time, it also causes a double problem of information reading leakage. risk

[0005] 2. The dual-frequency antenna using PET as the carrier is not fragile due to the non-fragile performance of the PET material. During use, the antenna can be perfectly separated from the physical product again for secondary reuse.
