A kind of double-frequency electronic labelTechnical field
The utility model is related to radio frequency arts, more particularly to a kind of double-frequency electronic label.
Background technology
Common dual-frequency label is all to be combined together completion by a high-frequency label and a ultrahigh-frequency tag, in cityAll there is the problem of performance is unstable in the dual-frequency label circulated on field, its reason is between high frequency and ultrahigh-frequency tag two mostlyDistance one change, performance will produce great changes, the failure such as lead to not to use, influence Consumer's Experience.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of integrated double-frequency electronic label so that high frequency is with surpassingThe distance between high-frequency label is stable, and double frequency performance is stable.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of double-frequency electronic label, including RF antenna structures, high frequency identification chip and hyperfrequency identification chip, it is described to penetrateFrequency antenna structure, the high frequency identification chip and the hyperfrequency identification chip are printed on base material, the RF antenna structuresIt is electrically connected with respectively with the high frequency identification chip and the hyperfrequency identification chip.
Wherein, the RF antenna structures include first structure section, the second structural sections and the 3rd structural sections.
Wherein, the first structure section is the Back Word structure of multilayer nest.
Specifically, the high frequency identification chip is arranged in Back Word structure.
Wherein, second structural sections include a rectangular configuration and changeover portion, wherein the changeover portion is double-U-shaped kinkingStructure, the changeover portion is connected with first structure section.
Wherein, the 3rd structural sections include a rectangular configuration and changeover portion, wherein the changeover portion is double-U-shaped kinkingStructure, the changeover portion is connected with first structure section.
Wherein, wherein one jiao of the rectangular configuration at the 3rd structure end is fillet.
Wherein, the hyperfrequency identification chip is arranged on the junction of second structural sections and the 3rd structural sections.
Wherein, the base material is potsherd.
Wherein, the RF antenna structures are one kind in aluminum antenna structure and copper antenna structure.
Using above-mentioned technical proposal, due to RF antenna structures being connected with high frequency chip and UHF chips respectivelyConnect so that no matter how to adjust aerial position, the position where both it remains constant, i.e. double frequency performance can be all the timeKeep stable, Consumer's Experience is good.

In figure, 1- RF antenna structures, 11- first structures section, the structural sections of 12- second, the structural sections of 13- the 3rd, 2- high frequenciesIdentification chip, 3- hyperfrequency identification chips.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted thatExplanation for these embodiments is used to help understand the utility model, but does not constitute to restriction of the present utility model.ThisOutside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not constitute conflict each otherIt can just be mutually combined.
As first embodiment of the present utility model, a kind of double-frequency electronic label is proposed, as shown in figure 1, including radio frequency dayCable architecture 1, high frequency identification chip 2 and hyperfrequency identification chip 3；Wherein, RF antenna structures 1 include first structure section 11, theTwo structural sections 12 and the 3rd structural sections 13, first structure section 11 are the Back Word structure of multilayer nest, and its pin is arranged on backThe innermost circle of word structure, high frequency identification chip 2 is also disposed at the innermost circle of Back Word structure, and passes through welding pin and first structureSection 11 is connected, i.e. first structure section turns into high frequency antenna structure.Second structural sections 12 include rectangular configuration and changeover portion, changeover portionFor double-U-shaped kinking structure, changeover portion is connected with first structure section 11；3rd structural sections 13 also include rectangular configuration and changeover portion, squareThe adjacent angular that shape structure is connected with changeover portion is fillet, likewise, changeover portion is double-U-shaped kinking structure, changeover portion and first structureSection 11 is connected, and the second structural sections 12 and the 3rd structural sections 13 constitute ultra-high frequency antenna structure, and its pin is arranged on the second structural sections12nd, the junction of the 3rd structural sections 13 and first structure section 11, hyperfrequency identification chip 3 is also disposed at the second structural sections 12 and theThe junction of three structural sections 13 and first structure section 11, is connected by welding with the pin of high frequency antenna structure.
RF antenna structures 1, high frequency identification chip 2 and hyperfrequency identification chip 3 are printed on ceramic base material and (not shown in figureGo out) on, RF antenna structures 1 use copper antenna structure.
Those skilled in the art it is recognised that RF antenna structures 1 can also using aluminum antenna structure or other haveThe metal of identical electrology characteristic.
Using above-mentioned technical proposal, due to RF antenna structures being connected with high frequency chip and UHF chips respectivelyConnect so that no matter how to adjust aerial position, the position where both it remains constant, i.e. double frequency performance can be all the timeKeep stable, Consumer's Experience is good.
Embodiment of the present utility model is explained in detail above in association with accompanying drawing, but the utility model is not limited to be retouchedThe embodiment stated.For a person skilled in the art, it is right in the case where not departing from the utility model principle and spiritThese embodiments carry out a variety of change, modification, replacement and modification, still fall within protection domain of the present utility model.
