The UHF RFID electronic nameplate tag comprises a tag and a radiation sheet, wherein the radiation sheet is arranged at the upper part of the tag, the tag and the radiation sheet are coupled to form an integral tag, a coupling ring, a chip and a matching inducer are arranged on the lower side of a PCB (Printed Circuit Board) of the tag, and the radiation sheet 7 is an FPC (Flexible Printed Circuit Board) substrate. The UHF RFID electronic nameplate tag provided by the invention has the advantages that since the radiation sheet is arranged at the upper part of the tag and adopts the FPC substrate, not only can the impedance matching requirement be satisfied, but also the nameplate tag can satisfy two required important properties, i.e., metal resistance property and flexibility of fitting with different metal surface shapes.
Description
Technical field
The present invention relates to electronic label technology field, be specifically related to a kind of RFID electronic nameplate label.
Background technology
In the utilization of UHF RFID label tag, often encounter situation label sizes, pliability being had to rigors, such as embed the label of metal surface, the nameplate (2) being provided with label is normally fixed on metal (1) surface by rivet (3) by this label, as depicted in figs. 1 and 2.Because product label must meet two key properties: (1) anti-metal characteristic, the pliability of (2) laminating different metal surface configuration.For meeting this two characteristics, for label design proposes very harsh requirement.
General routine be the product label of base material by stupalith, the effect of anti-metal can be reached, but cannot use having the enterprising enforcement in the metal surface of curvature because ceramic label material hardness is high, and be in use very easy to because collision causes the cracked of ceramic label, thus cause tag defeat.These problems cause very large difficulty for the popularization in actual applications of UHF RFID product label.
Summary of the invention
In order to overcome the problems such as the pliability difference of existing product label existence, the invention provides one and possessing anti-metal characteristic and laminating different metal surface configuration flexible UHF RFID electronic nameplate label simultaneously.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of UHF RFID electronic nameplate label, comprise label 14 and radiation fin 7, label 14 top is provided with radiation fin 7, label 14 forms overall label with radiation fin 7 by being coupled, and the downside of the PCB8 of label 14 is provided with coupling ring 11, chip 9 and coupling inductance 10.
Described radiation fin 7 is FPC base material.
The chip 9 of described label 14 with mate inductance 10 side and form MOLDING processing layer 12 by MOLDING process.
Described label 14 is installed in the label hole 5 of metal 1.
UHF RFID electronic nameplate label of the present invention, label top is provided with radiation fin, and radiation fin adopts FPC base material, can meet impedance matching requirements as above, can meet again product label and must meet two key properties: the pliability of anti-metal characteristic and laminating different metal surface configuration.

Embodiment
The ultimate principle of UHF RFID label tag is as follows, and as shown in Figure 3, right side is the equivalent electrical circuit of label chip to the equivalent electrical circuit of label chip and label antenna, and left side is the equivalent electrical circuit of label antenna; When antenna and each self-impedance conjugate pair of label are seasonable, RFID label tag realizes best impedance matching.Wherein:
Label antenna impedance is:
Label chip impedance is:
Conjugate relation is:
,
.
With reference to shown in Fig. 4, for certain label chip in market, adopt ADS software to carry out impedance emulation to its chip equivalent electrical circuit, Fig. 5 is emulation gained label chip impedance real part curve, and at 920MHz frequency place, its impedance real part value is 27.1 ohm.Fig. 6 is emulation gained label chip imaginary impedance curve, and its imaginary impedance value of 920MHz frequency place is-199.8 ohm.So the impedance of label antenna is according to conjugate condition, and should be that impedance real part is equal or close, imaginary impedance is opposite number each other, is optimum matching.
The present invention proposes the product label scheme of a kind of UHF RFID, impedance matching requirements as above can be met, product label can be met again and must meet two key properties: (1) anti-metal characteristic; (2) pliability of different metal surface configuration of fitting.
UHF RFID electronic nameplate label scheme general idea of the present invention is as follows:
1. be positioned on metal 1 surface the label hole 5 that diameter 4mm-20mm, degree of depth 1mm-4mm are dug in middle, fixing rivet hole 4, label hole 5 for placing label 14, as shown in Figure 7.
2. dig the nameplate hole 6 of long 40mm-100mm, wide 3mm-20mm at nameplate center, when making to install, label hole 5 is positioned at the inside center place in nameplate hole 6, and nameplate 2 is fixed on metal 1 by rivet 3, as shown in Figure 8.
