Abstract
The utility model discloses a vehicle electronic tag with UHF frequency band, and the technical problem needs to be solved is to facilitate the use of the tag in an electronic toll collection system. The utility model adopts the following technical scheme; the vehicle electronic tag with the UHF frequency band comprises a tag casing, a ceramic substrate is adhered in the tag casing through a double-sided adhesive tape, an antenna and a chip are arranged on the ceramic substrate, the antenna is a dipole antenna and arranged on the front surface of the ceramic substrate, a feeding end thereof adopts two convex structures, and narrow slots are respectively formed on two arms of the antenna. Compared with the prior art, the vehicle electronic tag adopts the dipole antenna with two arms which are formed with the slots, thereby enhancing the ability of being read of the tag under the condition of limiting signal strength, and reducing the mis-reading probability; and furthermore, the tag adopts the brittle ceramic substrate and the antenna is paved on the whole ceramic substrate, thereby greatly improving the anti-disassembly performance of the tag. The tag is applicable to various vehicles and has the advantages of stable performance, easy batch processing and convenient installation.
Description
Technical field
The utility model relates to a kind of electronic tag, particularly a kind of electronic tag that is applicable to 900MHz～930MHz frequency range.
Background technology
Electronic tag is the component units of radio-frequency recognition system.Along with the expansion of applying in radio frequency identification, no-stop charging system is applied more and more.No-stop charging system is applied in bridge, high speed crossing etc., and the input ratio of its system itself is bigger.In no-stop charging system, the vehicle electric label is a The key factor.Because the kind of vehicle is a lot, the inclination angle of height of car and vehicle windscreen is also inequality, like this adaptability of label is had higher requirement.Stolen for preventing label, the tamper performance that is bonded in the label on the vehicle also there is certain requirement.
Summary of the invention
The purpose of this utility model provides a kind of vehicle electric label of uhf band, and the technical matters that solve is to make things convenient for label to use in no-stop charging system.
The utility model is by the following technical solutions: a kind of vehicle electric label of uhf band, has the label shell, be pasted with ceramic substrate by double faced adhesive tape in the label shell, ceramic substrate is provided with antenna and chip, described antenna is a dipole antenna, be arranged on the front of ceramic substrate, its feed end adopts two " protruding " shape structures, and antenna two arms respectively have finedraw.
The length of the utility model finedraw is 900MHz～930MHz for satisfying electronic tag adaptation frequency.
Ceramic substrate of the present utility model is of a size of 82mm * 50.5mm * 0.6mm.
Antenna size of the present utility model is 80mm * 47mm.
" protruding " of the present utility model shape physical dimension is 7.5mm * 3mm.
Label chip of the present utility model is welded between two " protruding " shape structure.
Label shell sizes of the present utility model is 86mm * 54mm * 3mm.
Double faced adhesive tape of the present utility model is of a size of 80mm * 50mm * 0.18mm.
The label of the present utility model back side is pasted with another double faced adhesive tape.
Another double faced adhesive tape of the utility model is of a size of 80mm * 50mm * 0.8mm.
The utility model compared with prior art, the dipole antenna that has adopted two arms to crack, strengthen label and limited the ability that is read under the signal strength conditions, reduced and misread probability, this label adopts frangible ceramic substrate, because antenna has been paved with whole ceramic substrate, improved the tamper performance of label greatly again.This label is applicable to various vehicles, stable performance, and easily batch machining is easy for installation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the antenna assumption diagram of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is further elaborated.As shown in Figure 1, the vehicle electric label that uhf band of the present utility model uses, adopting thickness is that the PC plastics of 3mm are as label shell 1, be equipped with ceramic substrate 2 in it, adopt double faced adhesive tape 5 that ceramic substrate 2 is fixed in the label shell 1, the electronic tag back side is provided with another double faced adhesive tape 6, and convenient and vehicle windscreen bonds together.
As shown in Figure 2, ceramic substrate 2 fronts are provided with antenna 3 and IC chip 4.Antenna 2 adopts silver slurry silk-screen dipole antenna, adopts two " protruding " shape structures at feed end, and antenna two arms respectively have the finedraw 7 of certain-length, can obtain the antenna of different frequency and directional diagram by the length of regulating this slit 7.Label chip 4 is welded between two " protruding " shape structure.
As most preferred embodiment, label shell 1 is of a size of 86mm * 54mm * 3mm, and the specific inductive capacity of ceramic substrate 2 is 9, and ceramic substrate 2 is of a size of 82mm * 50.5mm * 0.6mm, and double faced adhesive tape 5 is of a size of 80mm * 50mm * 0.18mm.The ceramic substrate 2 positive silver slurry silk-screen dipole antenna circuit that adopt, be of a size of 80mm * 47mm, each " protruding " shape structure is covered the copper layer and is of a size of 7.5mm * 3mm, and the IC chip is arranged in the middle of two " protruding " shape, adopts scolding tin that chip pin and on-chip silk-screen antenna circuit are welded together.Regulate the length in the slit 7 on label antenna two arms during Installation and Debugging, realize regulating the frequency and the directional diagram of antenna, obtain adapting to the electronic tag that frequency is 900MHz～930MHz.
The vehicle electric label of uhf band of the present utility model, applied range, stable performance, easy batch machining, cost is low, installs and uses.
