Abstract
The utility model relates to an inductively coupled feed bending passive electronic tag antenna with adjustable resonance frequency. Both sides of a chip connection coil are provided with inductively coupled feed bending antennas different in the size of rectangular waveforms. The inductively coupled feed bending 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; the third advantage that the needed resonance frequency can be achieved though adjusting the length and the width, and sizes of real and imaginary parts of the impedance can be independently adjusted and inputted according to the need for impedance matching, thereby enabling 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 the adjustable induction coupling feed bending passive electronic label antenna of a kind of resonance frequency, 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 induction coupling feed bending passive electronic label antenna of commodity anti-theft in the market.
Design: in order to realize above-mentioned purpose of design.Chip connecting coil both sides are the design of the induction coupling feed meandered antenna that differs in size of square waveform, are technical characteristics of the present utility model.the purpose of doing like this is: this had both been responded to coupling feed bending passive electronic label antenna and had been made of metal foil coil and the sensing chip that square waveform differs in size, not only by adjusting the humorous bat brick frequency that length and wide size can reach to be needed, and can be according to the needs of impedance matching, independently regulate the size of input impedance real part and imaginary part, 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 induction coupling feed bending passive electronic label antenna, chip connecting coil both sides are the induction coupling feed meandered antenna that square waveform differs in size.
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, not only can reach the humorous bat brick frequency of needs by adjusting length and wide size, and can according to the needs of impedance matching, independently regulate the size of input impedance real part and imaginary part, make tested signal strength signal intensity higher, reliability is higher, and monitoring effect is better, and anti-theft effect is better.

Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.A kind of induction coupling feed bending passive electronic label antenna, chip connecting coil 1 both sides are the induction coupling feed meandered antenna 2 and 3 that square waveform differs in size.The metal foil coil that induction coupling feed meandered antenna is differed in size by square waveform and sensing chip 3 consists of and plane distribution on PET film 5.Plane distribution on PET film 5 induction coupling feed meandered antenna 2 and 3 and 5 of PET films be equipped with adhesive phase 4, 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.
Claims (3)
