Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
The principle of Radio Frequency Identification (RFID) is that a reader and a tag perform non-contact data communication to achieve the purpose of identifying a target. The application of RFID is very wide, and typical applications include animal chip, automobile chip burglar alarm, entrance guard control, parking lot control, production line automation and material management. The radio frequency identification technology realizes non-contact two-way communication by combining radio wave non-contact quick information exchange and storage technology and wireless communication with data access technology and then connecting a database system, thereby achieving the aim of identification. In the identification system, reading and writing and communication of the electronic tag are realized through electromagnetic waves. According to the communication distance, the data exchange mode between the read/write device and the electronic tag can be divided into near field and far field, and accordingly, the data exchange mode is divided into load modulation and backscatter modulation, which is considered to be one of the most promising information technologies in the 21 st century.
With the development of RFID technology, the requirements for the performance of electronic tags are higher and higher. The anti-metal electronic tag is an electronic tag packaged by a special anti-magnetic wave-absorbing material, and technically solves the problem that the electronic tag cannot be attached to a metal surface for use. The product can be waterproof, acid-proof, alkali-proof and anti-collision, and can be used outdoors. The metal-resistant electronic tag can obtain good reading performance even farther than the reading distance in the air when being attached to the metal. By adopting special circuit design, the electronic tag can effectively prevent metal from interfering radio frequency signals, and the real anti-metal electronic tag has the following outstanding performances: the reading distance of the metal paste is farther than that of the metal paste, which is an excellent result of the overall design. The metal-resistant electronic tag is very wide in application and higher in corresponding performance requirement just based on the excellent performance of the metal-resistant electronic tag.
In the existing method, the anti-metal electronic tag is generally designed in the form of a common dipole antenna pad height or a microstrip antenna, and the tag is thick in size and inconvenient to use in the mode of the dipole antenna pad height; the microstrip antenna is influenced by the antenna structure 30, generally has narrower bandwidth and lower gain, the center frequency point of the anti-metal electronic tag produced under the influence of the production process can generate certain deviation, and the tag identification performance difference is larger; on the other hand, the anti-metal label is difficult to achieve the anti-disassembly design due to the structural characteristics of the anti-metal label.
Aiming at the problems of narrow bandwidth, low gain and poor anti-disassembly performance of the existing anti-metal electronic tag antenna, the invention provides a novel anti-metal electronic tag, and the invention increases the bandwidth of the electronic tag by arranging a plurality of parallel slotted holes at one end of a radiation plate, for example, a U-shaped groove 3024 antenna consisting of two slotted holes, and reserves the structural design of an anti-disassembly adhesion hole 101 to realize the anti-disassembly of the anti-metal tag. For convenience of explanation, the following explanation is made of the scheme of the U-plane antenna.
Fig. 1 is a system configuration diagram of a metal-resistant electronic tag according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a metal-resistant electronic tag, including: a label adhesive layer 10, an electronic label and antenna structure 30; the electronic tag is positioned between the tag adhesive layer 10 and the antenna structure 30; the antenna structure 30 includes a radiation plate, one end of the radiation plate penetrates through the body of the radiation plate 3021 and is provided with a closed U-shaped slot 3024 with an opening pointing to the other end of the radiation plate 3021; a tamper-proof adhesive hole 101 is reserved in an area of the label adhesive layer 10 facing the electronic label.
In the embodiment of the present invention, in the prior art, the RFID metal-resistant electronic tag is generally designed and manufactured by four methods, that is:
1) Raising a common dipole antenna tag;
2) Adopting a mode of adding wave-absorbing materials into common labels;
3) A substrate with an electromagnetic band gap UBG structure is used as a dielectric plate of the antenna;
4) A design method of a microstrip antenna.
Among them, the first three methods generally have high cost and large volume, and are not suitable for being applied to surfaces of large-scale equipment. The microstrip antenna generally includes a dielectric substrate, a radiator, and a ground plate. The thickness of the dielectric substrate is far smaller than the wavelength, the metal thin layer at the bottom of the substrate is connected with the grounding plate, and the metal thin layer with a specific shape is manufactured on the front surface of the substrate through a photoetching process to be used as a radiator. The shape of the radiating fins can be varied in many ways according to requirements. The rise of microwave integration technology and new manufacturing processes has pushed the development of microstrip antennas. Compared with the traditional antenna, the microstrip antenna has the advantages of small volume, light weight, low profile, easy conformality, easy integration, low cost, suitability for batch production, electrical property diversification and the like. Therefore, the design method of the microstrip antenna is very suitable for the anti-metal electronic tag. However, microstrip antennas also have certain problems, such as relatively narrow bandwidth and high Q value; the loss is large and surface waves are excited, resulting in a reduction in radiation efficiency; the performance is greatly influenced by the material of the dielectric substrate, and the like. These disadvantages in turn affect the identification performance of the electronic tag.
In view of the above, the solution of the present invention needs to overcome the above disadvantages while using microstrip antenna to design the anti-metal tag antenna structure 30. Preferably, in order to improve the adaptability of the anti-metal electronic tag, a U-shaped antenna is adopted to realize the broadband of the tag. The anti-metal characteristic can be met, meanwhile, the tag bandwidth can be greatly expanded through the U-shaped groove 3024 antenna structure 30, and the environmental adaptability of the tag is improved.
In the embodiment of the present invention, as shown in fig. 2, the structure 30 of the antenna of the U-shaped groove 3024 in combination with the metalized via is selected, and the main purpose is to change the current path on the radiating plate, so that the resonance point moves to a low frequency, and a relatively flat return loss is formed. On the other hand, the U-shaped groove 3024 and the metalized via hole at the edge are connected to serve as a resonant radiator, so that a plurality of current paths on the radiating plate are in resonant matching, and the bandwidth is further expanded. The purpose of widening the frequency band of the microstrip antenna is achieved by generating multi-point resonance. Furthermore, the bandwidth of the microstrip antenna is widened, the consumption of materials is reduced, the cost is reduced, and the reliability is improved.
Preferably, the antenna structure 30 includes: an antenna substrate 301 and an antenna body 302; the antenna body 302 is attached to the antenna body.
Preferably, as shown in fig. 3, the antenna body 302 includes: a radiation plate 3021 located on the surface of the antenna body 302 for signal radiation; an antenna base plate 3022 located between the antenna substrate 301 and the electronic tag chip 20 for fixing an antenna; a metalized via 3023 extending through the antenna substrate 301 for connecting the radiating plate 3021 to the antenna base plate 3022.
In the embodiment of the present invention, the antenna substrate 301 is filled with a teflon composite material or an FR-4 glass fiber board, so that the antenna substrate has good dielectric constant performance and heat-resistant and moisture-proof performance, thereby ensuring the stability of the tag.
Preferably, a plurality of the metalized vias 3023 are present on the antenna substrate 301.
Preferably, the metalized via 3023 is filled with a conductive metal.
Preferably, as shown in fig. 4, the radiation plate 3021 and the antenna base 3022 are fixed based on a filler metal adhesion.
In the embodiment of the present invention, the metallized holes have various functional requirements, such as conducting the signal generated by the electronic tag chip 20 to the radiation plate for emitting the signal. The radiation plate and the electronic tag chip 20 are isolated by the dielectric substrate, and a corresponding conductive path needs to be constructed to conduct the signal. Based on this, a plurality of metalized vias 3023 are preset, and conductive metal is filled in the metalized vias 3023, so that signal conduction can be realized. On the other hand, the filling metal and the radiation plate need to be fixed by adhesion between the filling metal and the antenna base plate 3022, so that the plurality of metalized vias 3023 can achieve multipoint fixation, and ensure structural stability.
Preferably, the metalized via 3023 is also used for transmitting a signal generated by the electronic tag chip 20 to the radiation plate 3021.
Preferably, the size of the long side of the U-shaped groove is not less than 1/2 of the size of the long side of the radiation plate 3021.
In the embodiment of the present invention, in order to ensure the multi-point resonance effect, the size of the long side of the U-shaped groove should not be too small, and is preferably set to be not less than 1/2 of the size of the long side of the radiation plate 3021.
The embodiment of the invention provides a method for manufacturing an anti-metal electronic tag, which comprises the following steps: fixing the electronic tag on the tag bonding layer 10, and forming an anti-disassembly bonding hole 101 in the area of the tag bonding layer 10 opposite to the electronic tag; the antenna structure 30 is laid above the electronic tag, and during the laying process, a metal filling operation is performed on the metalized via hole 3023 in the antenna structure 30.
Preferably, the label attachment layer 10 is double-sided adhesive backed.
In the embodiment of the present invention, the function of the label bonding layer 10 is to ensure that the electronic label is bonded and fixed with a corresponding attachment object during use. On the other hand, it is also necessary to ensure fixation between the antenna base 3022, the electronic tag chip 20, and the corresponding tag adhesive layer 10. Based on this, it is necessary to design the corresponding label adhesive layer 10 as a double-sided adhesive to realize double-sided fixation.
Preferably, the antenna body 302 includes: a radiation plate 3021 located on the surface of the antenna body 302 for signal radiation; an antenna base plate 3022 located between the antenna substrate 301 and the electronic tag chip 20 for fixing an antenna; a metalized via 3023 extending through the antenna substrate 301 for connecting the radiating plate 3021 to the antenna base plate 3022.
Preferably, a U-shaped slot structure is formed at one end of the antenna structure 30.
Preferably, a plurality of the metalized vias 3023 are present on the antenna substrate 301.
Preferably, the metal filling operation includes any one of an electrocautery metal filling operation or a metal grouting operation.
Preferably, the metal used in the metal filling operation is a conductive metal.
In the embodiment of the invention, the radiation plate and the antenna floor need electric conductivity, so that the radiation plate and the antenna floor are made of conductive metal materials or plated with conductive metal films, and the adhesion and fixation between metals can be realized through electrocautery metal filling operation or metal grouting when the metals are filled.
Preferably, the electronic tag is fixed in a tamper-proof manner through a preset tamper-proof adhesive hole 101, so as to ensure the use safety of the electronic tag. In the existing anti-dismantling technology of the electronic tag, the technology of fragile paper and a hidden groove on a base material is mainly adopted, but the technology is generally applied to common non-anti-metal tags. In order to realize the anti-disassembly characteristic of the tag, the invention adopts a special structural design, the tag chip is placed on a bottom plate of the microstrip antenna, when the electronic tag is produced, a hole which is right opposite to a glue filling hole is formed on back glue which is right under the tag and is right opposite to the chip, when the electronic tag is used, epoxy resin AB glue is dripped into the glue filling hole and then is installed on the surface of an attachment, and after the epoxy resin AB glue is cured (catalyst is added, the best state can be achieved within 24 hours), the epoxy resin AB glue is firmly bonded with the chip and the attachment. When the tag is moved, the bonding force between the chip and the surface of the antenna is originally smaller than the bonding force between the epoxy resin adhesive and the chip and the adhesive, so that the chip falls off from the antenna, and the anti-dismounting effect is achieved.
