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
The present invention relates to a kind of metal electronic tag, this product is applicable on metal surface or human body and the belongings, belongs to the electronic label technology field.
Background technology
UHF plastic sheeting electronic tag is widely used as the information carrier of Internet of Things.UHF plastic sheeting electronic tag has good characteristic at nonmetallic surface, but in the metal surface, UHF plastic sheeting electronic tag can not be returned information to read write line by the influence of metal material, thereby causes electronic tag to lose efficacy.Metal object is seen everywhere in our daily life, how electronic tag is applied on the metal, and the usable range of widening label just seems very important.Human body also is a kind of conductor, and the characteristic of metalloid is arranged, and common UHF plastic sheeting electronic tag has interference near human body, has the situation that can not be identified when using as permit identification.Thereby anti-metal tag to be applied to permit identification with the obvious advantage.The electronic tag of present anti-metal field is mainly based on the ceramet label, and the material in the middle of the ceramet label is a ceramic body, and the front is the pattern of silver layer antenna, seals chip with glue, and the back side is that the whole piece silver layer is as the stratum.Ceramic body in the ceramet label is frangible, and the processing and debugging complexity because of the ceramet label is heavier, exists comfortable wearing poor when being applied to permit identification.
Summary of the invention
The purpose of this invention is to provide a kind of metal electronic tag, there is the deficiency frangible, that processing and debugging is complicated in the ceramet label that solves existing anti-metal field; Because of the ceramet label is heavier, exist comfortable wearing poor when being applied to permit identification.There is the weakness of comfortable wearing difference in the present invention when overcoming the shortcoming of the frangible and processing and debugging complexity of ceramet label and being applied to permit identification, only need to help widening the application of metal label by finely tuning antenna pattern to satisfy the different needs of each country.
The objective of the invention is to be achieved through the following technical solutions, a kind of metal electronic tag is characterized in that, described electronic tag is successively by the PET film, the aluminum antenna of die bonding, and foamed material and release liners constitute; The aluminum antenna is etched on the PET film, and the one side of foamed material is bonding through glue and PET film, and the another side of foamed material is through the bonding release liners of gum.
Chip adopts Monza 3 chips of DuraLink encapsulation.
The thickness of foamed material is 1-5mm.
The present invention changes the structure of the ceramet label of existing anti-metal field, designed the UHF aluminum antenna metal label that the aluminum antenna, foamed material and the release liners that are connected by PET film, chip successively constitute, PET film and foamed material are not only all very light among the present invention, and all be difficult for broken, production run is simple, and debugging has easily overcome the shortcoming of the frangible and processing and debugging complexity of existing ceramet label, be not only applicable to the metal surface, be applicable on human body and the belongings yet.Its frequency central point 3Db bandwidth reaches 5-20MHz.The present invention promptly satisfies the different needs of each country by the fine setting antenna pattern, helps widening the application of metal label, has very strong practicality.
Description of drawings
Fig. 1 is a decomposition texture synoptic diagram of the present invention;
Among the figure, 1PET film, 2 aluminum antennas, 3 chips, 4 foamed materials, 5 release liners.
Embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the present invention is made of aluminum laminated films antenna 2, foamed material 4 and the release liners 5 that PET film 1, chip 3 connect successively; Chip adopts Monza 3 chips of DuraLink encapsulation; The thickness of foamed material 4 is 1-5mm, and actual (real) thickness is according to the frequency range decision of using, and the one side of foamed material 4 is bonding through glue and PET film 1, and the another side of foamed material 4 is through the bonding release liners 5 of gum; Aluminum antenna 2 is etched on the PET thin layer 1, and the independent test reading of the present invention is apart from be 4.5m, is placed on the sheet metal test reading apart from being 4.5m.
Claims (3)
1. a metal electronic tag is characterized in that, described electronic tag is successively by the PET film, the aluminum antenna of die bonding, and foam material and release liners constitute; The aluminum antenna is etched on the PET film, and the one side of foam material is bonding through glue and PET film, and the another side of foam material is through the bonding release liners of gum.
2. metal electronic tag according to claim 1 is characterized in that, described chip adopts Monza 3 chips of DuraLink encapsulation.
