A dimensional microwave radiation area in a transverse H shape is arranged in an area of the sheet-shaped microstrip circuit in a generally rectangular shape. Two transverse connection circuits connecting with the mircrostrip circuit are arranged in a spaced and parallel manner in a middle portion of the transverse-H-shaped microwave radiation area, wherein one of the circuits is a connected connection circuit while the other of the circuits is an unconnected connection circuit having an interrupted part. The chip is connected to the interrupted part of the unconnected connection circuit in a bridging manner and connects with the unconnected connection circuit on the two sides.

And by using the chip having large memory capacity, the load of background running is reduced obviously, the message reading and writing time is saved, the background building and maintaining cost is reduced, and the management efficiency is improved.

Description

Electronic tag

Technical field

The utility model relates to a kind of electronic tag, particularly a kind ofly works in the passive RFID electronic label that uhf band can have very large memory.

Background technology

Development along with Internet of Things; Passive RFID (wireless radio-frequency) electronic tag is extensively applied to each social management field; It can satisfy under realistic application conditions read write line to by remote, multi-object, the robotization identification of marker, analyze and handle, improved the efficiency of management and level greatly.Traditional RFID electronic tag is because the structure of microstrip circuit and the reasons such as matching degree of microstrip circuit structure and chip; Cause microwave emission/receiving range shorter; And because the chip internal memory is little; The bulk information operation needs through reasons such as backstages, makes to receive many restrictions in actual use, causes inconvenience.

The utility model content

In order to solve the problem of above appearance; The utility model provides a kind of electronic tag; Particularly a kind of passive RFID electronic label that works in uhf band, has very large memory; Can improve the microwave emission/receiving range of electronic tag, and the microwave emission of whole electronic tag is more evenly distributed.

The electronic tag of the utility model; Substrate is provided with microstrip circuit and the chip that is connected with said microstrip circuit; In the zone of the rectangular sheet microstrip circuit of profile cardinal principle, be provided with the microwave radiation district that is I-shaped space substantially, be provided with two horizontal CCs that are communicated with microstrip circuit at the middle part in this I-shaped microwave radiation district with the parallel interval mode; Wherein one is the communication type CC; Another is for having the non-connection CC of discontinuity, and described chip cross-over connection is in the discontinuity place of non-connection CC, and is connected with the non-connection CC of both sides.This is the microstrip circuit structure of I-shaped microwave radiation district form substantially, can adjust the impedance of whole microstrip circuit, makes it to mate more with the impedance of chip, thereby improves the electronic label read-write effect, increases the distance of microwave emission/reception.Particularly,, electronic tag can be adapted to and jumbo chip, the for example capacity chip that can the reach 8K use (capacity of traditional die is hundreds of bit only) that is complementary through this structure.

On the said structure basis, described I-shaped microwave radiation district is preferably the longitudinal axis both sides that are arranged on the sheet microstrip circuit with symmetric mode.The microwave radiation district that this mode is provided with helps better mating with microstrip circuit impedance and chip impedance, makes the read-write better effects if of electronic tag.

Further, said this horizontal CC that is provided with the parallel interval mode is preferably near the mid point both sides that are arranged on the I-shaped microwave radiation district longitudinal axis length direction or its, i.e. the medium position place in this I-shaped microwave radiation district.

Further preferred version also comprises, has in the described communication type CC than the thinner narrow circuit linkage section of non-connection CC.Test shows, adopts the CC of two thickness different structures, can have even more ideal effect.

In addition, the another kind of optimal way on the said structure basis is with the discontinuity in the said non-connection CC, is arranged on the length mid point of this non-connection CC or near position it.The microwave radiation direction of considering chip is the characteristics along chip center's even scattering in the two poles of the earth to the left and right; Chip is arranged on the length mid point of non-connection CC or near position it; Make chip symmetrical apart from two ends; To help making the microwave radiation of electronic tag more even, and make read-write that better effect arranged information.

Above-mentioned microstrip circuit generally can be arranged on the substrate that is made up of PCB (surface-mounted integrated circuit), potsherd, PVC or nonwoven fabrics through modes such as printing, sintering, bonding or riveted structures.

Test shows, in the electronic tag of the utility model said structure, saves as the chip of 8KB memory capacity in being fit to very much be provided with; Jumbo chip internal memory can be stored more management information; Can directly read and operate during reading writing information, realize front end node service and management, alleviate the burden of running background system the information that is stored in chip internal memory the inside; Practice thrift and build and the background maintenance cost; And because read-write equipment is directly the information that is stored in the chip to be operated, also saved the time, improved the efficiency of management.

Further, on the another side of the above-mentioned substrate that is provided with microstrip circuit, can also be provided with can be for information about visual, with convenient identification and identification under specific circumstances.

The electronic tag of the utility model can improve the microwave emission/receiving range of electronic tag; And the microwave emission of whole electronic tag is more evenly distributed; And behind the chip that uses the high capacity internal memory, obviously alleviated the burden of running background system, saved the Card read/write time; Practice thrift and build and the background maintenance cost, improved the efficiency of management.

Below through by the embodiment of accompanying drawing illustrated embodiment, the foregoing of the utility model is remake further detailed description.But should this be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following instance.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 utility model.
