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 physical connection between the chip and the antenna of a conventional smart label. This connection is prone to abnormalities or damage during use, making the smart label unable to adapt to harsh use environments and reducing product life.

Abstract

The invention discloses a thin-antenna separated ultra-high-frequency intelligent tag which comprises a miniature ultra-high-frequency intelligent tag module, a coupled amplification antenna and a two-layer composite film, wherein the ultra-high-frequency intelligent tag module is arranged on one surface of an ultra-high-frequency antenna. The ultra-high-frequency intelligent tag module and the coupled amplification antenna are clamped in the middle so that the thin-antenna separated ultra-high-frequency intelligent tag has a waterproof function. Meanwhile, the tag bending requirements are satisfied. The thin-antenna separated ultra-high-frequency intelligent tag of the invention is especially applicable to 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 a thin antenna detached ultra-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 traceabi...
