Description
Technical field
The utility model relates to RFID applied technical field, in particular to a kind of anti-metal electronic tag.
Background technique
Radio frequency identification (RFID) technology is to carry out non-contact two-way communication using wireless radio frequency mode, to reach identification mesh
, and exchange the automatic identification technology of data.In the actual application of RFID, there is substantial portion of application all inevitable
Come into contacts with metal object.But applying in metal object surface, common RFID electronic label is pasted onto metal object
Body surface face or it is neighbouring when be often faced with performance it is weak in addition failure the problem of.In order to eliminate influence of the metal to electronic tag, need
Specially to design the electronic tag for being used in metal surface.And existing metal label then often exist price it is relatively high, peace
The disadvantages of dress mode is not simple enough, volume is larger.Thus limit RFID technique answering on a large scale in metal asset management field
With.
Utility model content
The utility model proposes a kind of anti-metal electronic tags, it is intended to which solving ordinary electronic label can not directly be placed with
Metal surface, higher cost, mounting means is complicated, the larger problem of volume.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of anti-metal electronic tag, slot antenna slot and flexible electronic label including being provided with metal covering, flexible electrical
Subtab includes short-circuited conducting sleeve, below the short-circuited conducting sleeve and the label chip that be electrically connected with the short-circuited conducting sleeve and be in symmetric shape
And the label antenna being electrically connected with the short-circuited conducting sleeve, the flexible electronic label are pasted onto the metal covering simultaneously by covering glue mode
Across the slot antenna slot, the label chip is located at the surface or underface of the slot antenna slot, the gap day
The size and impedance matching of the shape of wire casing and the flexible electronic label.
Further, the flexible electronic label further includes substrate, and the short-circuited conducting sleeve is attached to the substrate upper surface, institute
Label chip is stated to be electrically connected below the substrate with the coupling coil.
Further, the substrate is PET, paper or pcb board, and the substrate surface is etched with aluminium foil or copper foil.
Further, the flexible electronic tag length is greater than the width of the slot antenna slot.
Further, the shape of the slot antenna slot is symmetrical rectangular wave or waveform.
Further, the length of the slot antenna slot is greater than 50mm.
Further, width range 1mm~50mm of the slot antenna slot.
Further, the size of the short-circuited conducting sleeve is not more than 30mm*30mm.
A kind of anti-metal electronic tag for implementing the utility model, has the advantages that so that lower-cost general
Logical flexible electronic label is affixed directly to the metal surface equipped with slot antenna slot in which can be convenient, and has excellent performance；
Cost is significantly reduced, and facilitates installation and electronic tag size is small, so that low cost management metal assets become possibility.
Detailed description of the invention
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail, in attached drawing:
Fig. 1 is the structural schematic diagram of the electronic tag of the utility model anti-metal；
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
As shown in Figure 1, a kind of anti-metal electronic tag, slot antenna slot 1 and flexible electronic including being provided with metal covering 2
Label 3, flexible electronic label 3 include substrate, short-circuited conducting sleeve 6, positioned at label chip short-circuited conducting sleeve 6 lower section and be electrically connected with short-circuited conducting sleeve
4 and in symmetric shape and the label antenna 5 that is electrically connected with short-circuited conducting sleeve 6, flexible electronic label 1 is pasted onto metal by covering glue mode
Face 2 and across slot antenna slot 1, label chip 4 is located at the surface or underface of slot antenna slot 1, the shape of slot antenna slot 1
The size and impedance matching of shape and the flexible electronic label 1.
Slot antenna slot 1 is a gap good using cutting technique preprocessing on metal surface, which punches
Metal plate upper and lower surface.The shape of slot antenna slot 1 is symmetrical rectangular wave or waveform.The width of slot antenna slot can be with
Change between 1mm~50mm, preferably 10mm or so, the processing line of rabbet joint total length of slot antenna slot 1 generally 140mm~
Between 190mm, the length of slot antenna slot 1 is generally higher than 50mm after rectangular wave or undulated design.Slot antenna slot 1
As metal label antenna and exist, the length of slot antenna slot 1 can be used for adjusting the impedance matching of label to enhance performance.
The width of slot antenna slot 1 can according to actual processing need be adjusted, the width of general gap antenna slot 1 take smaller value in order to
Processing, the influence to tag performance are smaller.
The design of flexible electronic label 3 has short-circuited conducting sleeve, and the size of the short-circuited conducting sleeve is generally no greater than 30mm*30mm.Flexible electronic
Label 3 is using PET, paper base material or pcb board as substrate, and substrate surface is etched with aluminium foil or copper foil, and short-circuited conducting sleeve 6 is attached to institute
