Problems solved by technology

[0003] Ordinary high-frequency tags are generally made of aluminum-etched antennas. Due to the limitation of aluminum materials, the size of aluminum-etched high-frequency tags is generally more than 10*15mm, and it is impossible to make small or miniature antennas. This is what those skilled in the art do not expect to see of

Embodiment 1

[0028] Such as Figure 1~3 As shown, this embodiment relates to a miniature high-frequency tag, specifically, the miniature high-frequency tag includes an electronic chip 3, a base layer 1 and an antenna 2; the antenna 2 is located above the base layer 1, and the electronic chip 3 is installed on the antenna 2 , and the electronic chip 3 is electrically connected to the antenna 2; wherein, the antenna 2 is a copper etched antenna, which is because the copper etched antenna is corrosion-resistant and more stable than the aluminum etched antenna, and can be made into a smaller antenna (such as small or miniature antennas), and then can reach a smaller tag size to form a miniature tag; and because the antenna in this embodiment is a high-frequency antenna, it can form a miniature high-frequency tag.

[0029] In one embodiment of the present invention, the base layer 1 may be made of glass, polymer, or ceramics. Preferably, the base layer 1 is made of PI or PET.

[0030] In a pre...

Embodiment 2

[0034] Such as Figure 4 Shown, the present invention also provides a kind of preparation method of miniature high-frequency tag, comprises the steps:

[0035] Step S1, providing a base layer; preferably, the material of the base layer is PI resin or PET resin.

[0036] Step S2, forming a layer of copper film on the surface of the base layer. Specifically, the step of forming a layer of copper film on the surface of the base layer is: firstly provide a layer of copper film, and then apply an adhesive layer on the copper film, and then apply A copper film coated with an adhesive layer is attached to the upper surface of the base layer.

[0037] Step S3, performing an etching process on the copper film to form a copper-etched antenna; specifically, the step of performing an etching process on the copper film to form a copper-etched antenna is as follows: performing an etching process on the copper film by using an antenna pattern provided with a wire line to form a copper-etche...

Abstract

The invention relates to the technical field of electronic tags, and particularly relates to a miniature high-frequency tag and a preparation method thereof. An etching copper antenna of the PI or PET base material and the high-precision size is adopted so that the tag is enabled to has the characteristics of being small in size structure, long in the service life, wide in range of application, stable in performance and high-temperature-resistant and corrosion-resistant. Besides, the miniature high-frequency tag can be used in the severe environment and the condition which cannot be realized by a large tag to realize an RFID read function.

Description

technical field [0001] The invention relates to the technical field of electronic tags, in particular to a miniature high-frequency tag and a preparation method thereof. Background technique [0002] Electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called readout devices, scanners, reading heads, communicators, and readers (depending on whether the electronic tags can rewrite data wirelessly). The space (non-contact) coupling of radio frequency signals is realized through the coupling element between the electronic tag and the reader; in the coupling channel, energy transmission and data exchange are realized according to the timing relationship. The basic structure of the electronic tag is a tag antenna and an electronic chip. The electronic chip is composed of a coupling element and a chip. Each tag has a unique electronic code. The high-capacity electronic tag has a user-writable storage space and is attached to the o...
