Description
Technical field
The present invention relates to Internet of Things and RFID tag technologies, and in particular to a kind of small-sized RFID tag of stud.
Background technique
Technology of Internet of things rapid development, RFID tag is the basis of Internet of Things industry, will also welcome the opportunity of a new round with
Challenge.In recent years, further expansion, more and more traditional industries will generate RFID product and need by the RFID tag market demand
It asks.
It is passive RFID tags using RFID tag the most universal, and accounts for most quantity in passive RFID tags
It is the RFID tag under common application environment, based on ultrahigh-frequency tag.The maximum clothes RFID tag of current usage amount is come
It says, RFID tag is used for the logistic storage application link of clothes, and manpower is greatly saved, and promotes logistic efficiency, reduces cost.
2018 by it is appreciated that be the first year in unmanned shop, major retail trade giant releases the unmanned quotient of oneself one after another
Shop.But RFID but fails the large-scale application for effectively pushing unmanned shop as the data medium for being sent to great expectations for many years.
Its reason is: adaptability of the ultra-high frequency RFID label on different commodity be not also it is ideal, be not able to achieve all commodity
All by RFID tag come identification information.Especially in the RFID tag of metal object surface installation, if without any place
Reason, label will be completely ineffective, can not work.The label handled by anti-metal, performance will also have a greatly reduced quality, cost
It can exponentially increase, influence client's large-scale application.
In order to which ultrahigh frequency electronic tag can be used in metal surface, the techies of RFID industry also very take hardship
The heart goes effort by every means, but produces little effect.
It can be seen that a kind of superior performance is provided, the RFID tag of economical and practical metal surface application be this field urgently
Problem to be solved.
Summary of the invention
For the problems of prior art, a kind of completely new RFID tag skill applied to metal surface is needed
Art scheme.We avoid radio-frequency devices work drawback, in conjunction with metal surface texture from the characteristic of RFID tag itself
Improvement, the ultra-high frequency RFID label solution that has excellent performance is realized with least cost.For this purpose, the present invention is mainly metal watch
Face application provides a kind of small-sized RFID tag of stud, to overcome the problems of prior art.
To solve the above-mentioned problems, the small-sized RFID tag of a kind of stud provided by the invention, comprising: chip and antenna,
It is characterized in that, the conductive pattern of the antenna is stud structure；The center of stud antenna is arranged in the chip
On line.
Further, the antenna is flexible etching antenna, and the conductive pattern is by the one of which in copper or aluminium
Material is constituted.
Further, the antenna is flexprint antenna, and the conductive pattern is by silver paste or electrically conductive ink
One of material is constituted.
Further, the antenna is rigid etching antenna, and the conductive pattern is formed by copper foil etching and processing.
Further, the antenna is provided with the pad of at least two connection chips on the line of centres of stud,
Two resonant tanks in parallel are formed with after chip welding.
Further, the chip and antenna bond pad are welded using reverse packaging process, and welding compound is unidirectional anisotropic
Conducting resinl.
Further, the chip and antenna bond pad are welded using reflow soldering process, and welding compound is tin cream.
Further, the chip and antenna bond pad are welded using ultrasonic wire welding procedure, and lead is gold
One of line, aluminum steel or copper wire, and protected by encapsulating compound.
Further, the label is ultra-high-frequency passive RFID tag.
Further, the working frequency of the label is between 860MHz-960MHz.
The small-sized RFID tag of a kind of stud that this programme is formed, only there are two resonant tanks to constitute for antenna, overall dimensions
It is small and exquisite, it does not take up space；Structure is simple, easily fabricated；It is easy to use, it is low in cost, it is suitble to industry large-scale use.
Detailed description of the invention
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the small-sized RFID tag schematic diagram of present example Plays stud.
Fig. 2 is the deformed small-sized RFID tag schematic diagram of stud of ellipse in present example.
Fig. 3 is the small-sized RFID tag schematic diagram of stud in present example after circular deformation.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
Referring to Fig. 1, the small-sized RFID tag schematic diagram of a kind of standard stud that this example provides.
As seen from the figure, the RFID tag mainly by insulating substrate 1, be attached to the stud antenna 2 and chip on 1 surface of substrate
3 are constituted.Insulating substrate 1 uses PET film in the present embodiment, and stud antenna is using the aluminium foil for being attached to PET film surface
Conductive pattern is formed by etch process.Intermediate in stud antenna connects figure, provided with 4 rectangular pads 21, weldering
Disk and chip 3 are welded by reverse packaging process, so that chip and antenna is formed resonant tank, above and below intermediate connection zones
Space forms two independent resonant cavities 11 and 12.The chip that this example uses is the M4QT chip of IMPINJ company, is penetrated
The frequency point of frequency function admirable, labeling task is set as 920-925MHz, is the practical frequency range of China RFID, and label is combining aperture
In use, sensitivity reaches -16dB,-three dB bandwidth reaches 30MHz for metal surface, and performance is excellent.The length and width ruler of antenna body
Very little is 28*24mm, and size is small and exquisite, can be independently operated, the metal surface that can also cooperate aperture, reach better using effect.
Referring to figs. 2 and 3, the scheme of the small-sized RFID tag of the stud, can be the shape of various shapes, and work is former
Manage identical, only shape is adjusted.Label equally by insulating substrate 1, be attached to the stud antenna 2 and core on 1 surface of substrate
Piece 3 is constituted.Intermediate in stud antenna connects figure, and provided with 4 rectangular pads 21, pad and chip 3 are by falling to seal
Dress technique is welded, and chip and antenna is made to form resonant tank, and the upper down space in intermediate connection zones forms two solely
Vertical resonant cavity 11 and 12.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
