Problems solved by technology

However, in the field of miniature anti-metal tags, there has always been a huge contradiction between volume, performance and cost
In the industry, ceramic dielectrics are usually used as the base material for antenna design to obtain better radio frequency performance, but ceramic materials are difficult to process and the production efficiency is low, so the overall production cost of the product will be high
Although the cost of electronic tags obtained by other processes will be reduced, their electrical properties are not good enough to meet user needs.

Embodiment Construction

[0050] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0051] This example provides a UHF, readable and writable miniature UHF anti-metal electronic tag, which is a passive backscatter tag that meets the air interface requirements of ISO / IEC 18000-6C, and its working frequency range covers 860 MHz– 928 MHz.

[0052] In mass production, several labels need to be designed in a large material layout, arranged in a matrix according to the process requirements, and then cut into independent electronic labels after completion.

[0053] see figure 1 , which is a schematic structural diagram of the miniature UHF anti-metal electronic tag. As can be seen from the figure, the radio frequency tag is mainly composed of:

[0054] The first antenna layer 11 is composed of conductive antenna patterns arran...

Abstract

The invention discloses a mini ultrahigh-frequency anti-metal electronic label and a manufacturing method thereof. The electronic label comprises first, second and third antenna layers, first, second and third dielectric layers, a chip and conducting holes. The electronic label also comprises a paster and a double faced adhesive tape with release paper, one side of the double faced adhesive tape is attached to the lower surface of the third antenna layer, the other side of the double faced adhesive tape is provided with the release paper, and during use, the release paper can be released and the corresponding side is attached to the surface of an object. On the basis of minimized design, a chip embedded reverse packaging technology is combined with a printed circuit board technology, so that the cost is reduced, the RF performance is high, and large-scale industrialization is enabled.

Description

technical field [0001] The invention relates to the field of electronic tags, in particular to a miniature ultra-high frequency anti-metal electronic tag. Background technique [0002] The theme of the development of electronic tags in the 21st century will be personalized applications, and its connotations include smart convenience, green safety. In the past 10 years, the technology of electronic tags has undergone tremendous progress, from the reduction of chip size to the substantial improvement of label performance, it is a revolution for electronic tag technology itself, and will also drive the generation of electronic tag manufacturing technology and production equipment. Change, make electronic tags more intelligent. [0003] It can be seen that with the development of the information age, the personalized design of electronic tag technology has become the development trend of today's industry. Existing technologies have gradually allowed pioneers to design a variet...
