Description
Technical field
The present invention relates to a kind of high frequency NFC labels for anti-metal medium, belong to electronic tag design field.
Background technique
RFID electronic label under metal environment often with using, when RFID electronic label is close to metal, due to metal
There is strong reflectivity to electromagnetic wave, so can weaken along with signal, card reading distance also can become closer, and severe jamming is then
The phenomenon that will appear card reading failure；Therefore, RFID high-frequency label (passive label) is attached to the body surfaces such as metal or be attached to
Adjacent locations have the place of metal device, and reader issues signal and is easy the eddy current decay effect by metal and makes signal strength
Weaken significantly, causes tag read distance to become close or read failure.Solution general at present is in electronic tag
The back side pastes upper one layer of very thick foam material, label is widened at a distance from metal surface, to reduce metal to the anti-of label
Penetrating property.But such design effect is bad.
Summary of the invention
Regarding the issue above, the present invention provides a kind of high frequency NFC label for anti-metal medium.
The object of the present invention is achieved like this, a kind of high frequency NFC label for anti-metal medium, including label sheet
Body, plane materiel, base stock, plane materiel, base stock are covered each by the front in label body, the back side；The front of label body is equipped with chip；Its
It is characterized in:
Front, the back side of the label body are respectively equipped with front aerial coil, reverse side aerial coil, the front aerial coil
Direction of winding and reverse side aerial coil direction of winding on the contrary, in the aerial coil of front positive surface antenna line width for 0.2mm ~
1.0mm, the line width of reverse side antenna is positive 1-3 times of positive surface antenna line width in surface antenna coil in reverse side aerial coil, positive day
Line coil, reverse side aerial coil alignment precision are less than 0.15mm；Front aerial coil, the riveting conducting of reverse side aerial coil, front
Connection is connected with the positive chip of label body in aerial coil；
Be additionally provided with absorbing material layer, absorbing material layer gluing in the front or the back side of label body, absorbing material layer with a thickness of
0.08 ~ 1.5mm, the absorbing material magnetic permeability in absorbing material layer is between 20 ~ 100；Absorbing material layer gluing is in label body
Front when, absorbing material layer is connected with front aerial coil, absorbing material layer gluing when the back side of label body, inhale wave material
The bed of material is connected with reverse side aerial coil.
The reverse side aerial coil is that 2 circle reverse side antennas are constituted.
Structure of the invention is reasonable, it is easy, easy to use to manufacture, and the one kind provided through the invention is situated between for anti-metal
The high frequency NFC label of matter reaches reduction label sizes by the design of label (label body) purl loop, and frequency point exists
13.56Mhz±0.5Mhz；The design of high-frequency label be by realizing signal communication after wire coil coiling, but label it is smaller around
The area of line is with regard to smaller, and the place that the frequency point of label will float to other than 16Mhz, label can not work normally, therefore be less than
22x22mm sized labels work normally higher to the design requirement of its product coiling under 13.56Mhz frequency point.
Through the invention, solution: use line width in the lines (positive surface antenna) of 0.2mm ~ 1.0mm, according to consistent
Direction carries out coiling, and since the size of product is smaller, when the coil in label body chip face has been expired, we are in antenna
Metal wire (reverse side antenna) direction opposite with front lines (positive surface antenna) is detoured at the back side, to realize coiling line
Cumulative, the area of covert increase product coiled wire-wound coil of circle, the coiling area of two times of small size label of realization；It finally will be positive and negative
Coil (front aerial coil, reverse side aerial coil) is riveted, and the communication of positive and negative coil is completed.
Design principle:
A) front aerial coil and reverse side aerial coil direction of winding are reverse；
B) line width of reverse side antenna is positive the multiple (1-3 times) of positive surface antenna line width in surface antenna coil in reverse side aerial coil,
If the line width of positive surface antenna is 0.3mm, the line width of reverse side antenna, which is just designed as 0.6mm., can promotion label positive and negative antenna
The resonance validity of coil coupling；
C) front aerial coil, reverse side aerial coil alignment precision are less than 0.15mm；
E) the circle number of the front aerial coil of frontal design is constant, and the reverse side aerial coil of reverse side setting is 2 circles.
Through the invention, in use, placed one layer of absorbing material between metal surface and label body, thus to magnetic field
It has an impact, alleviates metal surface to the negative effect for reading label, sensing capability of the enhancing radiofrequency signal to label.Production
When, the absorbing material layer with a thickness of 0.08 ~ 1.5mm is set towards the back side of base stock in label body, the suction in absorbing material layer
Wave material magnetic permeability between 20 ~ 100, lead by reverse side aerial coil and the absorbing material in absorbing material layer at the label body back side
It is logical.
Select absorbing material magnetic permeability during 20 ~ 100, thickness can be very good and mark in the material of 0.08 ~ 1.5mm
Label are matched, and influence of the metal surface to label is alleviated；
The design of high-frequency label purl loop, the coil (reverse side aerial coil) at the back side are combined, backside loop with absorbing material
(reverse side aerial coil) is connected with absorbing material, is equivalent to label and becomes larger, to realize that tag performance is stronger；
Backside loop and the communication way of absorbing material be by label (label body) with absorbing material in conjunction with using glue material,
It combines the oscillating magnetic field of the purl loop of label with metal magnetic field in absorbing material, promotes the efficiency of label, resist metal
To the mutual inductance effect of label.
Therefore, through the invention, label design increases purl loop (reverse side aerial coil), realizes small size tag performance
More；Increase absorbing material structure, realizes that high-frequency label alleviates metal surface to the negative effect for reading label on the metal surface
It answers, sensing capability of the enhancing radiofrequency signal to label；High-frequency label reverse side design coil is combined with absorbing material, back side line
Circle is connected with absorbing material, is equivalent to label and becomes larger, to realize that tag performance is stronger.
