Abstract
The utility model relates to a passive electronic tag coil capable of broadening the antenna impedance frequency band. An E-type coil is arranged inside the rectangular coil; and the connection points of the rectangular coil are connected via dumbbell type connection lines. The passive electronic tag coil capable of broadening the antenna impedance frequency band 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 the design of the antenna broadening structure enables detected signals to be higher in strength, reliability to be higher, monitoring effects to be better, and anti-theft effects to be better.
Description
Technical field
The utility model relates to a kind of passive electronic label coil with broadening antenna impedance frequency band, 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 passive electronic label line with broadening antenna impedance frequency band of commodity anti-theft in the market.
Design: in order to realize above-mentioned purpose of design.Be provided with the E type coil in the circle of square coil, the square coil tie point by the design that the dumbbell type connecting line connects, is technical characteristics of the present utility model.The purpose of doing like this is: the mutual induction amount that has both increased aerial coil, realized again the broadening of antenna impedance frequency band, after its resonance chip consists of resonant circuit, this resonant circuit can make that the detected intensity of passive resonance signal is higher, better effects if, play the effect of sign identification, item tracking, information gathering, satisfied that the market articles of price are monitored voluntarily, antitheft needs.
Technical scheme: a kind of passive electronic label coil with broadening antenna impedance frequency band, be provided with the E type coil in the circle of square coil, the square coil tie point connects by the dumbbell type connecting line.
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, the design of broadening antenna structure makes tested signal strength signal intensity higher, and reliability is higher, and monitoring effect is better, and anti-theft effect is better.
Description of drawings
Fig. 1 is the planar structure schematic diagram with passive electronic label coil of broadening antenna impedance frequency band.
Fig. 2 is the layer structure schematic diagram with passive electronic label coil of broadening antenna impedance frequency band.
Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.A kind of passive electronic label coil with broadening antenna impedance frequency band is provided with E type coil 2 in the circle of square coil 1, E type coil 2 is inserted mutually by two E type coils and consisted of.Square coil 1 tie point connects by dumbbell type connecting line 3.Square coil 2 by 3-4 circle width less than 2 millimeters metal forming circle plane distribution on PET film 5.The gap of plane distribution between the square coil 1 on PET film 5 is less than 1.2 millimeters.Square coil 1 and the PET film 5 of plane distribution on PET film 5 is 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.
