Problems solved by technology

The production efficiency of this kind of smart label is very low, the thickness of the product is relatively thick, the product cost is high, and the reliability of the product is also poor, so it is limited in the large-scale promotion in the industry
[0005] There is also a conventional paper tag smart label, or a single-layer composite PET smart label, because the label cannot produce sufficient resistance to the influence of external moisture, especially during high-temperature ironing, steam treatment, washing and other processes. It is easy to cause the failure of the smart label and affect the production

Embodiment 1

[0023] The high-temperature and waterproof UHF clothing smart label is composed of UHF antenna, UHF smart chip and two-layer composite film. Such as figure 1 As shown, the conductive pattern 3 of the UHF antenna is arranged on one surface of the film-type insulating material 1, and the conductive pattern is a dipole antenna arranged on the film-type insulating material obtained by an etching process. The antenna has a set of dual ports And two symmetrically arranged radiation electrodes, and the two ports of the input end are connected to the two electrodes of the smart chip 4. The closed circuit composed of the UHF antenna and the smart chip forms a set of series resonant circuit. The input impedance of the chip is conjugated to the impedance of the antenna, and its resonant frequency conforms to the frequency range of 840-960 MHz. The thickness of the insulating substrate of the UHF antenna is 50um, and the material is flexible and bendable. The conductive material of the ant...

Abstract

The invention discloses an ultra-high-frequency intelligent clothing tag which comprises an ultra-high-frequency antenna, an ultra-high-frequency intelligent chip and a two-layer composite film, wherein the ultra-high-frequency intelligent chip is arranged on one surface of the ultra-high-frequency antenna. The ultra-high-frequency antenna and the ultra-high-frequency intelligent chip are clamped in the middle through the two-layer composite film so that the ultra-high-frequency electronic tag has a waterproof function. Meanwhile, the tag bending requirements under a rubbing state during clothing washing are satisfied. The intelligent tag of the invention is especially suitable for the field of intelligent tags for clothing trademarks and labels.

Description

technical field [0001] The invention relates to the field of smart labels, in particular to an ultra-high frequency clothing smart label. Background technique [0002] The application of smart labels is gradually affecting people's living habits and consumption patterns. Smart labels are terminal data carriers that implement radio frequency identification (RFID) technology, which can identify specific targets and read and write related data through radio signals without the need for mechanical or optical contact between the identification system and specific targets. Commonly used communication frequencies include low frequency (125k~134.2K), high frequency (13.56Mhz), ultra-high frequency (433MHz, 900MHz and 2.4GHz), etc. Passive and active methods are used to achieve different communication distances. RFID readers are also divided into mobile and fixed. At present, RFID technology is widely used, such as: libraries, access control systems, food safety traceability, etc. ...
