Electronic tag used for metal

Abstract

The invention relates to an electronic tag used for metal, belonging to the technical field of the electronic tag. The electronic tag is characterized in that the structure of a ceramic metal tag in the existing metal resistance field is changed, a UHF (Ultra High Frequency) aluminum antenna metal tag successively composed of a PET (Polyethylene terephthalate) film, an aluminum antenna connected with the chip, a foam material and release paper is designed. The PET film and the foam material in the electronic tag are light, have small possibility of breaking, have simple production process and are easy to debug, thereby overcoming the defects that the existing ceramic metal tag is always broken and is complex to process and debug. The electronic tag is not only suitable for metal surface but also suitable for the human body as well as objects carried by people. The central point 3Db bandwidth of frequency is 5-20MHz. According to the electronic tag, different requirements of various nations can be satisfied by finely adjusting antenna shape, and the electronic tag is favourable for widening the application field of the metal tag and has strong practicality.

Description

technical field [0001] The invention relates to an electronic tag for metal, which is suitable for use on metal surfaces, human bodies and carry-on articles, and belongs to the technical field of electronic tags. Background technique [0002] UHF plastic film electronic tags are widely used as the information carrier of the Internet of Things. UHF plastic film electronic tags have good characteristics on non-metallic surfaces, but on metal surfaces, UHF plastic film electronic tags cannot transmit information back to the reader due to the influence of metal materials, resulting in the failure of electronic tags. Metal objects can be seen everywhere in our daily life. How to apply electronic tags to metals and broaden the scope of use of tags is very important. The human body is also a kind of conductor, which has the characteristics similar to metal. Ordinary UHF plastic film electronic tags will interfere with the human body, and may not be recognized when used as an ident...

Problems solved by technology

[0003] The purpose of the present invention is to provide an electronic tag for metal, which solves the shortcomings of fragile ceramic metal tags in the field of anti-metal and complicated processing and debugging; when applied to identification cards, the ceramic metal tags are heavy and have poor wearing comfort

The present invention overcomes the disadvantages of fragile ceramic metal tags and complex processing and debugging, and the weakness of poor wearing comfort when applied to identification cards. It only needs to fine-tune the shape of the antenna to meet the different needs of various countries, which is beneficial to broaden the application field of metal tags
