Abstract
The utility model relates to a folded-dipole passive electronic tag antenna. The chip signal end is respectively connected with wiring ends of a rectangular coil; and two sides of the bottom of the rectangular coil are respectively connected with rectangular antenna wings. The folded-dipole passive electronic tag antenna has the first advantage that the structure is simple and the manufacturing cost is low; the second advantage that pasting is facilitated by a merchant; and the third advantage that as the feedback signals are strong, the detected signals are enabled to be higher in strength, reliability is higher, monitoring effects are better, and anti-theft effects are better.
Description
Technical field
The utility model relates to a kind of folded dipole passive electronic label antenna, belongs to electronic tag and makes the field.
Background technology
Granted publication CN201196852Y, title " passive electronic label ", it bursts at the seams custom-designed butterfly type orientation and is connected with the Intelligent Passive microchip, be made into the label of the similar size of shape such as same bookmark, thin and thick, stick on the surface of testee, be used for receiving the signal that intelligent reader is issued, and the information of its storage inside is sent or writes.Consider false proof, antitheft requirement, its appearance adopts the papery encapsulation, is carved with and prevents tearing line, after stickup, in case will tear it down, will cause antenna to be connected disconnection with chip, and label lost efficacy; All solidify unique identification code in the chip of its inside, can not artificially change, guaranteed the uniqueness of label.It can be by remote, detection of dynamic, and information is readable to be write.Its weak point: the one, complex structure, manufacturing cost is high; The 2nd, the antenna mutual induction amount is little, and the impedance frequency band of antenna is narrow, is not suitable for the antitheft of commodity in the market.
The utility model content
Purpose of design: avoid the weak point in background technology, design a kind of simple in structure, low cost of manufacture and be exclusively used in the folded dipole passive electronic label antenna of commodity anti-theft in the market.
Design: in order to realize above-mentioned purpose of design.The chip signal end is connected with the square coil terminals respectively, and the square coil two bottom sides is connected with respectively the design of the back-shaped antenna wing of rectangle, is technical characteristics of the present utility model.the purpose of doing like this is: this both the directional diagram of folded dipole passive electronic label antenna take distributing point as symmetrical, distributing point is at the center of half-wave dipole, the impedance of its distributing point is pure resistance, the oscillator of two 1/4 wavelength is extended the center of going back to again, and link together, become a folded dipole passive electronic label antenna, after its resonance chip consists of resonant circuit, this resonant circuit can make the detected intensity of passive resonance signal higher, better effects if, play sign identification, item tracking, the effect of information gathering, having satisfied the market articles of price monitors voluntarily, antitheft needs.
Technical scheme: a kind of folded dipole passive electronic label antenna, the chip signal end is connected with the square coil terminals respectively, and the square coil two bottom sides is connected with respectively the back-shaped antenna wing of rectangle.
The utility model is compared with background technology, and the one, simple in structure, low cost of manufacture; The 2nd, be convenient to businessman and paste; The 3rd, time inspection signal is strong, makes tested signal strength signal intensity higher, and reliability is higher, and monitoring effect is better, and anti-theft effect is better.

Fig. 2 is the layer structure schematic diagram of dipole passive electronic label antenna.
Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.A kind of folded dipole passive electronic label antenna, the chip signal end is connected with square coil 1 terminals respectively, and square coil 1 two bottom sides is connected with respectively the back-shaped antenna wing of rectangle.The back-shaped antenna wing of rectangle by rectangle antenna induction sheet 2 and back-shaped line 3 consists of and plane distribution on PET film 5.The chip signal end of plane distribution on PET film 5 is connected with square coil 1 terminals respectively, and the back-shaped antenna wing of square coil 1 and rectangle and 5 of PET films are equipped with adhesive phase 4, and its manufacture craft is prior art, is not described herein at this.
What need to understand is: although above-described embodiment is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in protection range of the present utility model.
