Description

Multi-frequency composite electronic label

Technical field

The utility model relates to this a kind of RFID Electronic Tag Structure.

Background technology

RFID (Radio Frequency Identification, radio frequency identification) The Application of Technology is increasingly extensive, and according to different application field and/or actual demand, at present commonly used have high frequency (HF) electronic tag, ultrahigh frequency (UHF) electronic tag etc.The decipherment distance significant difference of different frequency electronic tag can surpass tens times of HF as the decipherment distance of UHF, and in addition, the information storage amount of different labels also has big gap, label to manufacture cost variance bigger.HF frequency electronic tag and UHF frequency electronic tag commonly used at present all can only use under corresponding high frequency or the ultrahigh frequency frequency with it separately respectively.Popularization and development along with the RFID technology, can realize that to electronic tag multi-frequency identification has proposed higher demand, and at present above-mentioned RFID electronic tag all is difficult to realize in concrete the application, particularly at electronic tag and adopt under the big situation of the certificate use amount of this electronic tag (for example great politics/social activities etc.), not only discern, check difficulty, and the consume significant of certificate material, and be difficult to reuse, cause waste.

The utility model content

At above-mentioned situation, the utility model will provide a kind of composite electronic label with multi-frequency identification, examination function, to satisfy the multi-frequency identification demand that electronic tag is proposed.

The utility model multi-frequency composite electronic label is that its chip is positioned at the center antimere of S shape with microstrip antenna S-shaped setting on substrate of UHF frequency electronic tag, and the antenna circuit of chip both sides is that the symmetrical half-surrounded of band saw dentalation extends; In the hollow part of a side half-surrounded antenna circuit of its S shape antenna, also the location is compounded with a HF frequency electronic tag.The half-surrounded antenna circuit of the UHF frequency electronic tag S shape antenna at the antenna circuit of this HF frequency electronic tag and place maintains spacing, and the chip of HF frequency electronic tag is to be arranged on the opening place of the half-surrounded antenna circuit at close place away from the mode of UHF frequency electronic label antenna circuit structure as far as possible, to avoid interference.Said electronic tag substrate can be common used materials such as macromolecule organic materials such as plastics, pottery, copper clad plate, resin fibre sheet (or film), papery sheet (or plate), nonwoven fabrics.

In the above-mentioned multi-frequency composite electronic label, the locator meams of this HF frequency electronic tag that is arranged in the half-surrounded antenna circuit hollow part of UHF frequency electronic tag S shape antenna one side can have the multiple choices mode, as can adopting embedded mode, or stacked mode etc.The material used according to each electronic tag, its location complex method can adopt corresponding hot melt, welding or mode such as bonding according to material character and characteristics.

On the said structure basis, in the antenna circuit place face of the UHF frequency electronic tag that is compounded with HF frequency electronic tag or the one side opposing with it, but can also be further also be provided with one and be coated with carrier structures such as card as visual informations such as printing word or pictures at lateral surface in the relative mode in plane, make multi-frequency composite electronic certificate, in eyesight that satisfies the people and optical identification, can also carry out radio frequency electric identification, realize near/read-write and option read-write at a distance.This type of certificate is easy to upgrade certificate information, when needs are changed related information content, only need change order and know card, or the information that writes respectively again in the electronic tag gets final product also replacing easily when electronic tag damages.Improved recognition efficiency so greatly, satisfied examination requirement, and, can also have enough to meet the need, reuse simultaneously, reduced the data cost greatly management function demands such as the classification examination of certificate, information privacy, data analyses to huge certificate amount, with low cost.

Said this is compounded with the UHF frequency electronic tag of HF frequency electronic tag and is coated with between the carrier structure of visual information, stacked back, its plane is fixed by outside envelope, and it is fixing also can to adopt hot melt, welding or bonding way that it directly is bonded with each other.

When outside above-mentioned multi-frequency composite electronic label, outside envelope being set, can adopt the seal sleeve structure of seal form disposably and permanently when removing as long-term the use, outside modes such as hot overlay film plastic packaging commonly used at present, can also adopt to have the outside envelope that can open/close the form of sealing, the latter is specially adapted to the replacing and the repeated use of or certificate card that short-term use provisional as meeting certificate card, provisional social activities certificate card etc.

For the label or the certificate that are compounded with electronic tag and visual information carrier structure simultaneously, but for ease of identification and the examination to visual information, but its outside envelope can be all or is the transparent material structure at the regional corresponding position that is covered of the visual information with the visual information carrier structure at least.

The above-mentioned multi-frequency composite electronic of the utility model label, be compounded in the same label by the electronic tag of suitable mode HF and UHF different frequency, both avoided its phase mutual interference dexterously, can adapt under different frequency again and work, and two labels can be distinguished independent the storage and read-write without interfering with each other, more can satisfy far away, the identification of nearly different distance and examination need, satisfy the automatic identification under the multiple situation, various demands such as repeated use and hierarchical security management, also improved identification greatly, the examination and the efficiency of management, reduce material consumption, reduce expenses.

Below in conjunction with the embodiment of accompanying drawing illustrated embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
