Thick antenna discrete ultrahigh frequency intelligent label

Abstract

The invention discloses a thick antenna discrete ultrahigh frequency intelligent label which comprises a miniature ultrahigh frequency intelligent label module, a coupling amplification antenna, an insulated fill film and a two-layer composite film. The ultrahigh frequency intelligent label module is arranged on one surface of an ultrahigh frequency antenna. The insulated fill film is disposed on the same surface of the ultrahigh frequency intelligent label module of the ultrahigh frequency antenna. The ultrahigh frequency intelligent label module, the insulated fill film and the coupling amplification antenna are sandwiched by the two-layer composite film, thus realizing the waterproof function of the thick antenna discrete ultrahigh frequency intelligent label and meeting label bending requirements. The thick antenna discrete ultrahigh frequency intelligent label provided by the invention is especially suitable for fields of apparel trademark intelligent labels, tag intelligent labels, irregularly shaped intelligent labels and the like.

Description

technical field [0001] The invention relates to the field of smart labels, in particular to a thick antenna separation type 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 ...

AI Technical Summary

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.
