Elongated ultra-high-frequency induction label compounded from amorphous soft magnetic material

Abstract

The invention relates to an elongated ultra-high-frequency induction label compounded from an amorphous soft magnetic material, which comprises a first antenna and a second antenna, wherein the first antenna is used for ultra-high-frequency detection, and the second antenna is used for low-frequency detection and also used for enhancing the ultra-high-frequency detection performance of the first antenna; the first antenna is provided with a hole and a wireless radio-frequency chip, the hole is arranged on the middle part of the first antenna, and the wireless radio-frequency chip is arranged on the transverse middle lower part of the first antenna; the second antenna is provided with a substrate made of an amorphous soft magnetic material, and a plurality of magnetizing/demagnetizing sheets which are arranged alternately and made of a semihard magnetic material; and the magnetizing/demagnetizing sheets are attached to the same surface of the substrate. The substrate of the second antenna of the label provided by the invention is made of the amorphous soft magnetic material, and the amorphous soft magnetic material has high magnetoconductivity and especially has the highest magnetoconductivity in the low-frequency range of 1Hz-7500Hz, thereby ensuring the electromagnetic wave anti-theft function of the label; the label appears elongated, and has a small size, thereby being beneficial to ensuring the confidentiality; and in the high-frequency range, the attribute of the second antenna turns into metal, thereby enhancing the detection property of the first antenna and reducing the size of the label.

Description

technical field [0001] The invention relates to a long and narrow ultra-high frequency induction label composed of amorphous soft magnetic materials. Background technique [0002] In pharmacies, supermarkets, bookstores and other shopping malls, due to the small size of retail goods, it is easier to be carried out, which will cause economic losses to the merchants. Therefore, it is a general concern of merchants to solve the problem that retail goods are not "stolen" when sold in shopping malls such as bookstores, pharmacies, and supermarkets. At the same time, with the emergence of the Internet of Things, the requirements for logistics control and management of the quantity of goods are becoming more and more prominent. At present, in the anti-theft or management technology of commodities, books, etc., the electronic tags used for the anti-theft of commodities are usually low-frequency tags. UHF has a wide range of effects and fast data transmission speed, and can usually...

AI Technical Summary

Problems solved by technology

The UHF tags in the prior art are often too large to be hidden. If the anti-theft tag is integrated with the UHF data storage tag, it is easy to be found and torn off, thus affecting the management of commodities.
