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
[0006] There must be a connecting substance between the chip and the antenna of a conventional smart label. This kind of connecting substance is prone to abnormality or damage during use, which makes the smart label unable to adapt to the harsh use environment and shortens the product life.

Embodiment 1

[0028] The high-temperature and waterproof thin-type high-frequency smart label with separated antenna is composed of a miniature high-frequency smart label module, a coupling amplifying antenna and a two-layer composite film. like Figure 4 As shown, the antenna 3 of the coupled amplifying antenna is arranged on a surface of the film-type insulating material 1, and the antenna adopts a multi-circle coil which is obtained by electroplating and is arranged on the edge of the film-type insulating material, and an internal terminal of the coil and a plate capacitor The lower electrode 11 is connected, and the other external terminal is connected across the winding wire and the upper electrode 12 of the plate capacitor through a set of jumper wires 6. The insulating ink 5 is used to isolate the jumper wire 6 and the winding wire to prevent short circuit; An insulating ink 13 is used to form a dielectric layer between the electrodes and the upper electrode, and the thickness of the...

Embodiment 2

[0034] The room temperature and waterproof type is composed of a miniature high-frequency smart label module, a coupled amplifying antenna and a two-layer composite film. like Figure 5As shown, the coupled thin-type antenna separated high-frequency smart label and amplified antenna consists of two sets of coils connected in series in phase, and connected in series with a flat-plate capacitor to form a complete LC series resonant circuit. frequency work. The main antenna 3 and the auxiliary antenna 31 of the coupled amplifying antenna are arranged on one surface of the film-type insulating material 1, the main antenna adopts the multi-circle coil that is arranged on the edge of the film-type insulating material obtained by the aluminum etching process, and the auxiliary antenna adopts aluminum etching The multi-circle coil inside the main antenna is set on the film-type insulating material obtained by the process. The flat-plate capacitor uses the front and back conductive la...

Abstract

The invention discloses a thin antenna discrete high-frequency intelligent tag which comprises a miniature high-frequency intelligent tag module, a coupled amplification antenna and a two-layer composite film. The high-frequency intelligent tag module is arranged on one surface of a high frequency antenna. Through the two-layer composite film, the high-frequency intelligent tag module and the coupled amplification antenna are sandwiched in the middle, thus achieving the waterproof function of a thin antenna discrete high-frequency electronic tag and meeting tab bending requirements. The thin antenna discrete high-frequency intelligent tag provided by the invention is especially applicable to the field of intelligent tags for apparel trademark and hangtags.

Description

technical field [0001] The invention relates to the field of smart labels, in particular to a thin antenna separation type high-frequency 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 traceab...
