The utility model has advantages of simple structure, easy producing, convenient using, wide frequency band, and a recognition distance above 10 meters; the utility model is applicable for railcar management, aviation passenger and freight transportation, highroad vehicles management, logistics, propagation breeding management, archives management, access control system, security and safeguard, anti-fake labels, etc.
Description
Technical field
The utility model relates to a kind of radio-frequency recognition system, in particular, relates to a kind of knot type label antenna.
Technical background
Active label of the prior art needs external lithium battery supplying energy.Dead battery or need send when being out of order is returned and is made manufacturer's charging, changes, and safeguards inconveniently, and cost is higher, and discarded lithium battery contaminated environment.In addition, the active label complex structure, volume is big, leaks in actual applications and knows and the misclassification rate height.But there are shortcomings such as complex structure, narrow bandwidth decipherment distance be nearer in the label antenna that the part passive label adopts.
Chinese patent application number: 01128898.1 discloses a kind of radio-frequency label antenna, it is compared with existing electronic label antenna, having communication distance increases, bandwidth increases, but manufacture craft is relatively complicated, cost is higher, and needing increases vacuum metal film plating technology on coating substate, and high volume production process has slight environmental pollution.And its tellite is sheet glass or potsherd, and is easily broken in processing, transportation, installation and use process, thereby increases use cost.
Chinese patent application number: 972002777.7 disclose a kind of electronic label antenna, solved the technical barrier of wireless data transmission to the clock frequency sensitivity, but its manufacture craft is relatively complicated, frequency band is narrow, but decipherment distance is nearer, and range of application is subjected to bigger restriction.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of simple in structure, easy to manufacture, easy to use, bandwidth, decipherment distance knot type label antenna far away are provided.
Knot type label antenna of the present utility model, comprise substrate, be printed with knot sheet, feed transmission line and IC welding position on the described substrate, one end of described feed transmission line links to each other with the IC welding position, the other end links to each other with the narrow limit of knot sheet, narrow limit outwards enlarges, and loads a rectangle frame endways, and described whole label antenna is with the symmetry axis left-right symmetric by center, IC welding position and vertical feed transmission line.
Described substrate is an ordinary epoxy resin glass fibre single-side coated copper plate, and gross thickness is 1.6mm, and wherein copper plate thickness is 0.03mm; Described feed transmission line live width is 2 ± 0.1mm; The narrow limit of described knot sheet and feed transmission line are wide and outwards be extended to 35mm, and load the wide rectangle frame of 2mm that is endways; Described IC selects radio frequency tag chip for use.
The utility model has following beneficial effect compared with prior art:
(1) knot type label antenna frequency band can reach 13%, and coupling is good.In air dielectric, when tag read-write equipment power output minimum (10dBm) time, effective decipherment distance 〉=5m of label; During read write line power output maximum (0dBm), effective decipherment distance 〉=10m of label.With compare from the like product of U.S.'s import, frequency band is widened 2～3 times, under equal transmitting power, the utility model increases more than 30% than effective reading/writing distance of imported product;
(2) substrate material is selected common epoxy resin single-side coated copper plate for use, and stable performance is not fragile, and lower cost for material;
(3) the manufacture craft flow process is simple and easy, does not need vacuum metal film plating technology, helps environmental protection, helps large-scale production, and constant product quality, and cost of manufacture is low, helps wide popularization and application;
(4) simple in structure, easy to use, bandwidth, far away, the applied range of decipherment distance have big promote significance to the development of key industries such as traffic, logistics, safety guard.
