Description
Technical field
The invention belongs to technical field of RFID, be specifically related to a kind of anti-medium ultra-high frequency RFID label.
Background technology
RF identification (RadioFrequencyIdentification, RFID) is that one utilizes wireless radio frequency mode to carry out noncontact bidirectional data communication, to reach target recognition and to exchange the technology of data.The frequency range that domestic RFID system uses is broadly divided into several big classes such as low frequency (below 135kHz), high frequency (13.56MHz), hyperfrequency (UltraHighFrequency, UHF) (860～960MHz) and microwave (more than 2.4GHz).RFID system is generally made up of label, read write line and computer communication network.Label stores the relevant information of object to be identified, is attached on object to be identified, and in the process of real work, the performance of label can be directly subjected to the impact of the pasted medium in its back, affects very serious under many circumstances, and even resulting in label cannot work.At present for the research of ultra-high frequency RFID label, mostly rest on common label, anti-metal tag, anti-medium (include but not limited on the objects such as glass, plastics, rubber can normal operation) design of label and proposing still for blank.
With the present invention closest to the design that scheme is anti-metal tag, microstrip antenna needs ground plane due to its antenna structure, therefore can using metal surface as its ground plane, such that it is able to be used for realizing the design of anti-metal tag antenna, inverse-F antenna or planar inverted-F antenna are similar with microstrip antenna, it is also desirable to ground plane realizes its antenna function, but antenna smaller ingeniously, generally have only to the 1/4 of wavelength, therefore, be widely adopted the basic prototype as anti-metal tag antenna design.Additionally, Chinese scholars uses various different shape design, complete the design of different anti-metal tags.
The RFID tag of hyperfrequency and anti-metal tag have only taken into account a part of environment of labeling task, and in actual application, development particular with technology of Internet of things, industry technology of Internet of things, the use environment of label becomes increasingly complex, current technology scheme can not solve problems, therefore, how solving label working condition under complex dielectrics environment is this area technical problem urgently to be resolved hurrily.
Summary of the invention
It is an object of the invention to provide a kind of anti-medium ultra-high frequency RFID label, it is possible to the not normal operation by its back media environment interference.
The invention provides following technical scheme:
A kind of anti-medium ultra-high frequency RFID label, including: label media plate, anti-media label antenna pattern and IC chip；Described anti-media label antenna pattern is arranged on described label media plate, and described IC chip is arranged in the middle of anti-media label antenna pattern.
Described anti-media label antenna pattern is be provided with an I shape space in the middle of rectangle, and described I shape space includes top, intermediate gaps and bottom, and described top is shorter than bottom, and the intermediate gaps in described I shape space is provided with IC chip.
Described anti-media label antenna pattern is by printing or etching and processing is on medium.

Accompanying drawing explanation
Accompanying drawing is for providing a further understanding of the present invention, and constitutes a part for description, is used for together with embodiments of the present invention explaining the present invention, is not intended that limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the anti-medium ultra-high frequency RFID label of the present invention.
Detailed description of the invention
As it is shown in figure 1, back medium to be modeled to one block of dielectric-slab (the main parameter considered is material, dielectric constant, length, width and height), together it is simulated emulation with label, adjusts tag parameter, make performance reach optimum.Present invention achieves suitable in back dielectric-slab dielectric constant is the dielectric-slab of 1-10, comprises but is not limited only to glass, rubber, plastics etc..
Principle is: when one block of dielectric-slab is added at the back of label time, the change of the dielectric constant of dielectric-slab directly affects the size of electric capacity, because C=is ε rD2/14.4d, (wherein d is the average thickness of dielectric-slab, D is the average diameter of dielectric-slab), and f=1/2 П RC, namely have impact on the frequency of labeling task.
A kind of anti-medium ultra-high frequency RFID label, including: label media plate 1, anti-media label antenna pattern 2 and IC chip 3；Anti-media label antenna pattern 2 is arranged on label media plate 1, and IC chip 3 is arranged in the middle of anti-media label antenna pattern 2.
Anti-media label antenna pattern 2 is provided with an I shape space in the middle of rectangle, and I shape space includes top, intermediate gaps and bottom, and top is shorter than bottom, and the intermediate gaps in I shape space is provided with ic core 3.
Anti-media label antenna pattern 2 is that technique is with Inlay label by the processes such as typography or etching to the flexible thin material material such as plastics；In the present embodiment, the mode mainly through cracking on metal adjusts antenna parameter；The IC chip adopted in the present embodiment is passive RFID chip；The back dielectric-slab adopted is dielectric constant material between 1-10.
In the present embodiment, label be sized to 53mm*19mm；Back dielectric-slab is sized to 150mm*140mm*3mm, and this dielectric-slab is sized to simulation size, can comprise the size more than 53mm*19mm* any thickness in real work；Label is close to above dielectric-slab, wherein label in producing flexible material used owing to thickness is very little and labeling task is negligible without impact；Label antenna itself is composed copper or composes aluminum etc.；Crack in antenna the top and centre position, and gap is parallel；Label antenna is omnidirectional antenna；Gain is about 2.4dB；Using S11 in the below-10dB bandwidth as label, relative bandwidth is 48%.
As fully visible, volume of the present invention is little, and gain is high, bandwidth, and reading efficiency is high, and production cost is low, is suitable to extensive use.
The foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature carries out equivalent replacement.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
