As RFID system is applied more and more in all trades and professions, RFID electronic label is because being interfered, with card reader
Between communicating interrupt and unrecognized problem increasingly highlights, the electronic tag especially used on some hardwares,
Such as: boiler label, large and medium-sized elevator annual inspection mark label, pressure vessel steel cylinder annual inspection label, cylinder for liquefied gas label, logistics collection
Vanning label etc..Since these RFID electronic label are all direct pastes on the surface of metal object, metal object surface can be right
Electromagnetic wave signal generates reflection and refraction, the incident electromagnetic wave signal that RFID electronic label emits in reception from front card reader
When, it can also receive the reflection from metal object surface below and refraction interference wave signal, the interference electricity of this opposite in phase
Wave is superimposed with incident electromagnetic wave, so that the received incident wave energy of label itself weakens significantly, causes label receiving sensitivity big
Width decline, if the interference strength of this back wave reach or close to incident intensity of wave 50% or more, caused by directly
As a result, be pasted onto metal object surface electronic tag and reader can operating distance shorten dramatically, or even can not carry out
The read-write of label information identifies.
For the electromagnetic wave for reducing or even overcoming this RFID electronic label to be subject in metal object surface use process
Reflection and refraction interference, improve the discrimination of electronic tag, increase the identification distance of electronic tag, the way of the prior art be
The absorbing material that one layer of homalographic is placed or pasted between RFID electric tag antenna and metal object, to prevent and absorption is worn
The incidence wave of absorbing material is crossed, while also preventing and absorbing the interference electricity for being reflected by metal object surface and being reflected electron label
Magnetic wave energy, the interfering energy that absorbing material absorbs causes magnet loop resonance and loop eddy-current loss, finally in the form of heat
It loses, makes metal watch body that the interference wave of electronic tag is effectively prevented and be absorbed.But it is existing to be applied to RFID electronics
The absorbent structure of label, generally existing production process is cumbersome, complex process, needs first to paste absorbent structure and pastes RFID electronics mark again
Label, complicated operation.
