Side where 11 close to the opening of rectangular coupling hoops 9, and it is flat to couple short side where metal tape line 11 is open with rectangular coupling hoops 9
Row；The both ends of the coupling metal tape line 11 are respectively connected with one section of bending metal tape line 12, i.e., AB and A1B1 in figure, Mei Yiduan
12 end of bending metal tape line is both provided with radiation arm 14, i.e. radiation arm CD in Fig. 3 and radiation arm C1D1 need
It is bright, for radiation arm CD, be made of two sections of metal tape lines of BC and BD, for radiation arm C1D1, device by
Two sections of metal tape line compositions of B1C1 and B1D1, the main function of radiation arm are to adjust 11 both ends bending metal tape of coupling metal tape line
The impedance matching effect of line 12 obtains preferable tolerance performance.

Property is strong.
Meanwhile the utility model can either adapt to the case where reading and writing device antenna is near field antenna, also can adapt to reader
The case where antenna is far field antenna：Specifically, when reading and writing device antenna is far field antenna, reading and writing device antenna forms electric field radiation,
It is formed by dipole arm by coupling metal tape line 11 and both ends bending metal tape line 12 and is carried out signal reception, by rectangular coupling hoops
9 realize inner ring matching, and to generate high-frequency current at chip, activation chip 10 works；When reading and writing device antenna is near field

Band line 11 is formed by dipole arm with both ends bending metal tape line 12 and is matched, and high-frequency current, activation are generated at chip
Chip 10 is started to work.
The design process of the utility model is as follows：In antenna stack 7, the bending metal tape at coupling metal tape line 11 and both ends
Line 12 is axisymmetricly shape, therefore dipole element arm can be regarded as by coupling metal tape line 11 and two bending metal tape lines 12, by
In the definition of dipole antenna, the fundamental resonance wavelength of dipole is the 1/2 of respective frequencies wavelength, i.e. λ/2=c/ (2*f) but by
It being attached to PET in antenna, on the materials such as art paper, his resonance wavelength can reduce, because when electromagnetic wave penetrates medium, resonance
Wavelength is influenced to reduce by medium, i.e.,εrFor relative dielectric constant.For jewelry label, to examine
Consider two kinds of situations, the first situation is the material, such as PET film, art paper etc. adhered to required for forming label, these attachments
Material the frequency deviation of label can be generated and influence for the first time, then it is also contemplated that label puts environment (pallet etc.), they are right
The secondary effect that the frequency deviation of label will produce.
It is not that can not just work completely after frequency deviation, but performance (farthest read away from) will drop for the label of RFID
It is low.Due to the diversity of pallet, we consider all influences in tag design, and the initially selection of resonance point
It relies primarily in the length of entire dipole arm, i.e., (12 length of adjustment bending metal tape line) increases dipole by way of folding
The length of son, the number of bending fold is more, and the length of dipole is longer, and corresponding resonant frequency is also lower, each dipole
The length of sub- oscillator arms is needed in λ/4 or so；It, can be by adjusting bending for every a kind of pallet under the structure of the application
12 length of metal tape line so that the length of each dipole element arm is in λ/4 or so, you can so that can when label practical application

Resistance RflWith inductance Lfl, form coupled structure between rectangular coupling hoops 9 and coupling metal tape line 11, coupling metal tape line 11 and
The bending metal tape line 12 at both ends forms Radiating dipole, can be equivalent to capacitance Crl-d, resistance Rrl-dWith inductance Lrl-d, have Fig. 4 can
Know, look from chip, the input impedance of antenna can be equivalent to：
Wherein, ZflIndicate the input impedance of rectangular coupling hoops：
Zfl=Rfl+jωLfl
YrlIndicate the input impedance of dipole：
Wherein, the π of ω=2 f, M is the coefficient of coup, by the width and coupling metal tape line 11 and square of coupling metal tape line 11
Gap width between 9 short side of shape coupling ring (short side where opening) determines.
And for entire tag system, label antenna collects the energy in external field, is then passed to chip, unlatching core
Piece, chip launch data again by label antenna, and label antenna carries the effect of a road conversion and energy transmitting-receiving；
If the internal resistance of chip is Zc, then antenna feed impedance ZinIt needs to realize conjugate impedance match, only label antenna with the internal resistance of chip 10
Entirety and the internal resistance of chip realize conjugate impedance match, the energy that chip is received can be only achieved maximum value, that is, realize farthest
It reads away from,, can be with after the length for determining dipole element arm for different RFID jewelry labels therefore in specific implementation process
By adjusting the size of rectangular coupling hoops 9 to complete the conjugate impedance match of chip internal resistance and label antenna.
To sum up, the RFID jewelry labels of the utility model, it is only necessary to it is simple to fold and be bonded and be fixed on jewelry,
Have the advantages that simple in structure, highly reliable；Meanwhile the structure design based on antenna stack so that RFID jewelry labels can fit
