Abstract
The invention discloses a subminiature UHF RFID electronic tag. An orientation resonant area is designed between symmetric dipole antennas at the two ends of an annular loop of the tag, and therefore the identification effect of the subminiature tag is improved.
Description
Technical field
The present invention relates to a kind of electronic tag, particularly microminiature UHF-RFID electronic tag.
Background technology
When electronic tag is implanted, often by the profile of article, limited, after label is implanted, due to the distortion of labeling, the recognition effect of label is affected.As Liquor application, when label is implanted bottle cap, the moulding that it is attractive in appearance, for the smooth leeway that label leaves few, so the area size of label, shape and recognition effect are the keys of application.
Summary of the invention
The present invention completes in view of the above problems, and its object is to provide a kind of microminiature UHF RFID electronic tag design, is subtracting as far as possible the undersized while, guarantees to greatest extent the recognition effect of label.
A kind of microminiature UHF RFID electronic tag of the present invention, between the symmetrical dipole antenna at label loop checking installation two ends, has a zone design that plays directed resonance effect, and can be for technique, engineering welding.
Described a kind of microminiature UHF RFID electronic tag, the structure of employing loop checking installation, symmetrical doubling double-dipole antenna and directed resonance range, to reduce as much as possible the area of whole label.
Described a kind of microminiature UHF RFID electronic tag, the crack of double-dipole antenna and directed resonance range, two ends are symmetrical, and directed resonance range geometric figure, size and gap width can be adjusted.The width of accurate Calculation crack is the key that promotes tag recognition rate.
Described double-dipole antenna is symmetrical geometric figure or curve, and size can be adjusted.
A kind of microminiature UHF RFID electronic tag of the present invention, is applicable to the surface of complicated appearance and modeling, and class is implanted as the label on Cap for spirit bottle.
Accompanying drawing explanation
Fig. 1 is a kind of microminiature UHF-RFID electronic tag of the present invention schematic diagram.
Symbol description:
1 ... UHF-RFID electronic label chip
2 ... loop checking installation
3 ... double-dipole antenna
4 ... directed resonance range
5 ... crack.
Embodiment
Below in conjunction with accompanying drawing and case study on implementation, the present invention will be further described.
As shown in Figure 1, be applied to the microminiature UHF RFID electronic tag on Cap for spirit bottle, symmetrical doubling double-dipole antenna 3, be arranged in the two sides of the loop checking installation 2 that is welded with UHF-RFID electronic label chip 1, and loop checking installation 2 and double-dipole antenna 3 are integrated.
With the directed resonance range 4 of loop checking installation 2 and double-dipole antenna 3 homogeneities, be clipped in the middle of double-dipole antenna 3, symmetrical.
Under above-mentioned project organization, by adjusting the physical dimension of double-dipole antenna 3 and directed resonance range 4, the width of accurate Calculation crack 5, can allow profile be not more than the electronic tag of 20mm * 12mm, has equally good recognition effect.
Claims (5)
1. a microminiature UHF RFID electronic tag, is characterized in that:
Between the symmetrical dipole antenna at described label loop checking installation two ends, there is a region of playing directed resonance effect, and can be for technique, engineering welding.
2. a kind of microminiature UHF RFID electronic tag according to claim 1, comprises multiple label chip, loop checking installation, double-dipole antenna, directed resonance range ingredient.
3. a kind of microminiature UHF RFID electronic tag according to claim 1, adopts the structure of loop checking installation, symmetrical doubling double-dipole antenna and directed resonance range.
4. a kind of microminiature UHF RFID electronic tag according to claim 1, the crack of double-dipole antenna and directed resonance range, two ends are symmetrical, and directed resonance range geometric figure, size and gap width can be adjusted.
5. a kind of microminiature UHF RFID electronic tag according to claim 1, described double-dipole antenna is symmetrical geometric figure or curve, and size can be adjusted.
