Abstract
The utility model discloses a no substrate RFID label antenna, including first aluminium foil layer, the downside on first aluminium foil layer is equipped with second aluminium foil layer, it is fixed through PET's compound glue adhesion between the bottom on first aluminium foil layer and the top on second aluminium foil layer. According to the substrate-free RFID tag antenna, the first aluminum foil layer and the second aluminum foil layer are fixedly adhered through the PET composite glue, so that the purpose of not using a substrate is achieved, the thickness of a product is reduced, and the flexibility of the product is improved; by using the PET composite glue, the aluminum foil layers after adhesion fixation can be conveniently stripped, and the application range of the product is improved.
Description
Technical Field
The utility model belongs to the technical field of the RFID tag antenna, concretely relates to no substrate RFID tag antenna.
Background
The RFID tag antenna is a transponder antenna of an RFID electronic tag and is a communication induction antenna. The finished RFID electronic tag transponder is generally formed with a chip. The RFID tag antenna is classified into a metal etching antenna, a printed antenna, a copper-plated antenna, etc. due to different materials and manufacturing processes. At present, the conventional antenna of the RFID tag uses PET as a permanent bearing substrate, an aluminum foil circuit on the surface can not be separated from the PET, and the conventional antenna of the RFID tag must be used simultaneously when in use. Therefore, a product which can be separated from the PET substrate and only the aluminum foil antenna is left is needed to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a no substrate RFID tag antenna to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a no substrate RFID label antenna, includes first aluminium foil layer, the downside on first aluminium foil layer is equipped with second aluminium foil layer, it is fixed through PET's compound glue adhesion between the bottom on first aluminium foil layer and the top on second aluminium foil layer.
The device is used for adhering and fixing the first aluminum foil layer and the second aluminum foil layer through the PET composite glue, so that the aim of not using a substrate is fulfilled, the thickness of a product is reduced, and the flexibility of the product is improved; by using the PET composite glue, the aluminum foil layers after adhesion fixation can be conveniently stripped, and the application range of the product is improved.
Preferably, the composite glue of the PET is internally provided with a three-well PP-543021, a curing agent and ethyl ester in sequence from top to bottom.
Preferably, the ratio of the three-well PP-5430, the curing agent and the ethyl ester in the PET composite glue is 6:2: 9.
Preferably, the thickness of first aluminium foil layer and second aluminium foil layer equals, and thickness is 10 um.
The utility model discloses a technological effect and advantage: the substrate-less RFID tag antenna is provided,
1. the first aluminum foil layer and the second aluminum foil layer are adhered and fixed through PET composite glue, so that the aim of not using a substrate is fulfilled, the thickness of a product is reduced, and the flexibility of the product is improved;
2. by using the PET composite glue, the aluminum foil layers after adhesion fixation can be conveniently stripped, and the application range of the product is improved.
Drawings
FIG. 1 is a schematic view of the structural connection of the present invention;
fig. 2 is a schematic structural diagram of the composite glue of PET of the present invention.
In the figure: 1. a first aluminum foil layer; 2. PET composite glue; 21. mitsui PP-5430; 22. a curing agent; 23. ethyl ester; 3. a second aluminum foil layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a no substrate RFID label antenna as shown in fig. 1-2, including first aluminium foil layer 1, the downside of first aluminium foil layer 1 is equipped with second aluminium foil layer 3, and is concrete, first aluminium foil layer 1 equals with second aluminium foil layer 3's thickness, and thickness is 10um, it is fixed through PET's compound glue 2 adhesion between the bottom of first aluminium foil layer 1 and second aluminium foil layer 3's the top, it is fixed to carry out the adhesion through PET's compound glue between first aluminium foil layer and second aluminium foil layer, reaches the purpose that does not use the base plate, has reduced the thickness of product, has also improved the pliability of product.
Specifically, the three-well PP-543021, the curing agent 22 and the ethyl ester 23 are sequentially arranged in the PET composite glue 2 from top to bottom, specifically, the ratio of the three-well PP-543021, the curing agent 22 and the ethyl ester 23 in the PET composite glue 2 is 6:2:9, the aluminum foil layers after adhesion and fixation are conveniently stripped from each other by using the PET composite glue, and the application range of the product is enlarged.
When the RFID tag antenna without the base material is used, the first aluminum foil layer 1 and the second aluminum foil layer 3 are adhered and fixed through the PET composite glue 2, so that the aim of not using a substrate is fulfilled, the thickness of a product is reduced, and the flexibility of the product is improved; by using the PET composite glue 2, the aluminum foil layers after adhesion fixation can be conveniently stripped, and the application range of the product is widened.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
