Description
Technical field
The utility model relates to technical field of RFID, is specifically a kind of ultrahigh frequency electronic tag.
Background technology
Electronic tag is also known as radio-frequency (RF) tag, transponder, data carrier; Reader is also called readout device, scanner, read head, communicator, read write line (depend on electronic tag whether can wireless rewrite data).Realize the contactless of radiofrequency signal by coupling element between electronic tag with reader to be coupled, in coupling channel, according to sequential relationship, realize transmission and the exchanges data of energy.Along with popularizing of Internet of Things, electronic tag is widely used the various occasions in people's life, such as, and the ETC of High-Speed Automatic charge; The automatic unlatching of parking lot railing and charge; Source and the sale whereabouts of Special food are inquired about and are followed the trail of; Etc..
The electronic tag of prior art generally comprises substrate, the signal line (i.e. antenna) be located on substrate, the chip that is electrically connected with signal line, described chip and signal line form a loop, and synchronous signal circuit has certain extension to strengthen the acceptance of signal.
It is interval all to there is a good frequency range of receiving and transmitting signal effect in electronic tag, the frequency range interval of common electronic tag is lower, and due to the usable range of electronic tag very wide, different occasions has different demands, very high in the frequency of some its signal of specific occasion, as the frequency of ultra-high frequency signal, reach 840 ~ 960MHz, the transmitting-receiving effect of ordinary electronic label can become very poor, obviously cannot meet the particular/special requirement of transmitting-receiving ultra-high frequency signal.Moreover when common electronic tag is attached on metal objects, signal can be subject to metal interference, susceptibility is poor, reception and transmission range is short, transmitting-receiving weak effect.In order to avoid metal interference, need the ABS material shell adding hard at electronic tag outward, like this, tagged overall cost can be increased.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of and receives and dispatches ultrahigh frequency electronic tag satisfactory for result to ultra-high frequency signal.
Technical solution of the present utility model is, a kind of ultrahigh frequency electronic tag with following structure is provided, it comprises substrate, be located at signal line on substrate and chip, signal line is one block of overall aluminium sheet, on aluminium sheet, hollow out has left vertical slot, left translot, right vertical slot, right translot and is communicated with translot, left translot right-hand member is communicated with left vertical slot lower end, left vertical slot is communicated with right vertical slot through being communicated with translot, right vertical slot upper end is communicated with right translot left end, left vertical slot upper end is higher than connection translot, and the lower end of right vertical slot is lower than connection translot; Aluminium sheet forms pin in left vertical slot upper end, the part be communicated with between translot and right vertical slot, and aluminium sheet is pin under right vertical slot lower end, the part be communicated with between translot and left vertical slot are formed, and the two ends up and down of chip are connected with upper and lower two pins respectively.
After adopting above structure, the utility model ultrahigh frequency electronic tag compared with prior art, has the following advantages:
Due to the specific configuration mode of this electronic tag signal line, namely adopt chip, lower pin, design that overall large area aluminium sheet, upper pin arrive the closed-loop path of chip again, make the desired frequency range of this electronic tag receiving and transmitting signal very high, especially desirable to the ultra-high frequency signal acceptable effect of 840 ~ 960MHz; And this signal line is made up of one block of aluminium sheet of entirety, area is large, and distance, the signal transmitting and receiving of signal transmitting and receiving are effective; Moreover the most of region due to this signal line is one block of uniform aluminium sheet of uniform thickness, and namely antenna is evenly distributed on substrate, thus make the integral thickness of whole electronic tag even, paste flatness good, easy to use.
As improvement, the back side of substrate is bonded with one deck PET film, the back side of PET film is bonded with one deck aluminum laminated films, PET film is 250 to 9 with the Thickness Ratio of aluminum laminated films, like this, when this label is attached to metal surface, PET film and aluminum laminated films superposition effectively can avoid the interference of metal pair signal, increase the distance of signal transmitting and receiving, improve susceptibility, enhance signal transmitting and receiving effect; And the PET film of interpolation and aluminum laminated films are the film of flexible material, its materials are also far fewer than the ABS material shell of prior art, and manufacturing cost also significantly reduces.
Accompanying drawing explanation
Fig. 1 be the utility model ultrahigh frequency electronic tag face structural representation.
Fig. 2 is the structure for amplifying schematic diagram of part A in Fig. 1.
Shown in figure 1, substrate, 2, chip, 3, aluminium sheet, 4, left vertical slot, 5, left translot, 6, right vertical slot, 7, right translot, 8, be communicated with translot, 9, upper pin, 10, lower pin.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model ultrahigh frequency electronic tag, it comprises substrate 1, establish signal line on substrate 1 and chip 2.Signal line is one block of overall aluminium sheet 3, and on aluminium sheet 3, hollow out has left vertical slot 4, left translot 5, right vertical slot 6, right translot 7 and is communicated with translot 8.Left translot 5 right-hand member is communicated with left vertical slot 4 lower end, and left vertical slot 4 is communicated with right vertical slot 6 through being communicated with translot 8, and right vertical slot 6 upper end is communicated with right translot 7 left end, and left vertical slot 4 upper end is higher than connection translot 8, and the lower end of right vertical slot 6 is lower than connection translot 8.Aluminium sheet 3 forms pin 9 in left vertical slot 4 upper end, the part be communicated with between translot 8 and right vertical slot 6, aluminium sheet 3 is pin 10 under right vertical slot 6 lower end, the part be communicated with between translot 8 and left vertical slot 4 are formed, and the two ends up and down of chip 2 are connected with upper and lower two pins respectively.
Signal line gets back to chip 2 through lower pin 10, aluminium sheet 3, upper pin 9 after chip 2 is drawn, and is closed into complete loop.
The back side of substrate 1 is bonded with one deck PET film, and the back side of PET film is bonded with one deck aluminum laminated films, and PET film is 250 to 9 with the Thickness Ratio of aluminum laminated films.PET film thickness as the present embodiment is 250 microns, and the thickness of aluminum laminated films is 9 microns.Find in actual use, the PET film of this thickness proportion and concrete thickness and the better effects if of aluminum laminated films anti-metal interference, and too can not increase thickness and the weight of electronic tag itself.
