Description

A kind of novel anti-metal tag

Technical field

This utility model relates to RFID applied technical field, particularly to a kind of novel anti-metal electronic tag.

Background technology

RF identification is a kind of contactless automatic identification technology.In RFID (RadioFrequencyIdentification, RF identification) system, generally it is made up of reader and label.Reader reads the information in label by less radio-frequency, and compared with conventional barcode, it is remote that it has reading distance, and reading speed is fast, non-visual recognition, supports the advantages such as fast reading and writing.RFID technique combines with the technology such as the Internet, wireless communication networks, tracking and the information sharing of article in global range can be realized, in various fields such as logistics supply chain, the production automation, public information service, traffic administration and Military Application, there is wide application space.Wal-Mart announced to take the lead in starting to enable RFID technique to replace original bar codes technique in the supermarket in its whole world in 2003.To improve its traditional supply chain management efficiency.And then, METRO also begins to business in the following shop based on RFID technique that Germany offers, and so far, RFID technique starts much more popular rapidly in the whole world.

RFID system operates mainly in the frequency ranges such as low frequency (LF), high frequency (HF), hyperfrequency (UHF) and microwave (MW).Low frequency and High frequency RFID systems mainly utilize inductive to complete recognition function, read close together, and hyperfrequency and microwave frequency band RFID system complete identification process mainly through electromagnetic wave propagation, have reading distance farther out.Wherein hyperfrequency (UHF) is due to frequency moderate, is particularly suitable for the use of long distance passive RFID system.In view of the huge applications potentiality of ultrahigh frequency RFID, various countries have issued relevant policies and the specification of ultrahigh frequency RFID in succession.

Although current RFID technique is rapid with application development, but still not mature enough.Mainly there is the reason of two aspects, be that the cost of RFID tag still cannot be reduced to the acceptable degree of all producers on the one hand, thus the mark of all items cannot be realized；Another aspect is the demand that RFID tag also cannot meet all industries at present, and especially some special fields, this also becomes the study hotspot of some colleges and universities and research institution.At present, the study hotspot of RFID tag includes RFID anti-metal tag, microminiaturized label, embedded label and omni-directional label etc., and along with RFID is more and more extensive in the application of warehouse logistic industry, the demand of anti-metal tag seems especially prominent.

Utility model content

The purpose of this utility model is in that, overcomes conventional labels problem of hydraulic performance decline when being affixed on metal surface, solves the problems such as label cannot read, tradition anti-metal electronic tag production cost is high, concordance is poor in metal surface.

For achieving the above object, this utility model is by the following technical solutions:

A kind of anti-metal electronic tag, including insulation label shell, insulation medium board, INLAY label；INLAY label comprises: insulating substrate, the label antenna being positioned on insulating substrate and the label chip being connected with label antenna；

Described label antenna includes two radiation arms and short-circuited conducting sleeve；Wherein, short-circuited conducting sleeve is provided with an opening, and label chip is arranged at the opening part of short-circuited conducting sleeve, is connected formation closed circuit with short-circuited conducting sleeve；Two radiation arms are connected to short-circuited conducting sleeve both sides；INLAY label is pasted on insulation medium board, is undertaken spacing by locating dowel, and label chip is positioned at dielectric-slab upper surface, is after assembled in insulation label shell, adopts ultrasonic technique to be packaged.

Preferably, described label antenna is pasted on insulation medium board, and chip is positioned at dielectric-slab front, forms pifa antenna.

Preferably, described insulating substrate is PET film or cardboard.

Preferably, described short-circuited conducting sleeve be shaped as rectangular box-like or " u "-shaped.

Preferably, described antenna is the metal conductor layer being covered on insulating substrate.

As preferably, described insulation medium board is polyfluortetraethylene plate or the insulation board of FR-4 insulation board or other materials, it is possible to for rectangle, circle or other geometries.

Compared with technology compare, the advantages such as it is remote that a kind of anti-metal tag that this utility model provides has reading distance, anti-metal.This utility model not only overcomes the shortcoming of original metal label reading distance on a metal object difference, and overcomes anti-metal tag and produce the limitation that cost is high and concordance is poor in enormous quantities, it is possible to be suitable for the application of whole world different geographical RFID industry.

Detailed description of the invention

Below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is described in detail.

As shown in Figure 1, Figure 2 and Figure 3, a kind of anti-metal tag that this utility model embodiment provides, including: insulation medium board 32, INLAY label 31 and shell 33.INLAY label 31 is positioned by locating dowel 23, is pasted on insulation medium board 32, adopts in ultrasonic technique encapsulation and shell 33.

INLAY label includes insulating substrate 14, be positioned on insulating substrate 14 label antenna 11 and the label chip 13 being connected with label antenna；Short-circuited conducting sleeve 12 is used for providing an inductance to carry out conjugate impedance match with label chip 13, additionally, be additionally operable to prevent electrostatic.

In the present embodiment, as preferably, antenna 11 whole installation rectangular in form, wherein, short-circuited conducting sleeve 12 is provided with an opening, and label chip 13 is arranged at the opening part of short-circuited conducting sleeve 12, is connected formation closed circuit with short-circuited conducting sleeve 12.

Specifically, electrical length and the short-circuited conducting sleeve 12 of described label antenna 11 are of a size of fixed dimension, and this fixed dimension is determined according to material and the resonant frequency of anti-metal tag.The shape of label antenna 11 can be any geometry cabling that can extend electrical length, as " bow " shape or " string " shape etc. can extend the geometric figure of edge length, by adjusting geometric edge length.In this utility model embodiment, the electrical length of the label antenna 11 being positioned at front is longer, the electrical length of the label antenna 11 being positioned at reverse side is shorter, and label antenna 11 mainly mates with the real part of label chip 13, and short-circuited conducting sleeve 12 mainly mates with the imaginary part of label chip 13.

Further INLAY label 31 is flexible material, has maturation process, can be mass, and INLAY label 31 is positioned by locating dowel 23, is affixed on by the mode pasted and is pasted on insulation medium board 32, and cost is lower than PCB and ceramic process, and conformity of production is good.

Fig. 4 illustrates the using method of this utility model anti-metal tag.As shown in Figure 4, the anti-metal tag 41 that this utility model embodiment provides is attached to metal object 42 surface；Just to RFID card reader 43.The frequency that can realize 915MHz is read, and reveals good reading distance at U.S. band table.
