Description
Technical field
The utility model relates to the electronic anti-fogery technology, relates in particular to the anti-demolition electronic tags structure based on the ceramic substrate of microwave radio identification RFID technology, can be used for fixing in car use on glass.
Background technology
RFID (Radio Frequency Identification), promptly RF identification is commonly called as electronic tag.Electronic tag is again by being important among the RFID, because its effect is to be used for the identify label of recognition object, its performance is fine or not, the cost height, and all the performance to total system has decisive influence.RFID in 860MHz～960MHz frequency range technology, it is far away to have a decipherment distance, dynamically reads characteristics such as the ability of information is strong down, has been used by increasing industry, and electronic tag replaces bar coded sticker has become inexorable trend.
Increasingly mature along with RFID technology, the kind of electronic tag is also overstepping the bounds of propriety many more, and the past all is entering of monitor vehicle by manual work at highway or some parking lots; Such method not only efficient is low; And easy error, the birth of electronic tag has brought new management mode to vehicle management; It makes management of vehicles not only more convenient, and more accurate.
For this reason, the applicant once proposed a kind of speed height of making an inventory, and was accurate, and had the patented claim of anti-theft feature, and number of patent application is 201120401375.0.
The utility model content
Based on the deficiency that above-mentioned background technology is sayed, the applicant proposes the another kind speed height of equally not only making an inventory, and accurately, and has the anti-demolition electronic tags of the ceramic substrate of anti-theft feature.
The technical scheme of the utility model is:
A kind of anti-demolition electronic tags of ceramic substrate comprises:
-ceramic substrate, the one side of ceramic substrate is printed with the antenna thin layer;
-antenna thin layer, the shape of antenna thin layer are to have vacancy section on the metal foil face, and vacancy section is made up of with 1 the hollow out passage that is communicated with the two the hollow out window of 2 symmetrical distributions;
-RFID chip, the ground connection that is electrically connected are fixed on the antenna thin layer;
-shell body is buckled on the above-mentioned ceramic substrate and fixes, and has certain cavity volume and comes ccontaining above-mentioned RFID chip, antenna thin layer and ceramic substrate.
Further, described ceramic substrate is printed with relatively on another back side of antenna thin layer and is carved with some grooves.Can significantly increase because of the ceramic substrate stress and deformation causes its ruined possibility through on ceramic substrate, forming groove, strengthen the tamper effect.
Further, the antenna thin layer that prints on the described ceramic substrate is the silver-colored thin layer that is formed by silver slurry silk-screen.
What further, the shape of described hollow out window preferably adopted is rectangle.Certain, the shape of described hollow out window can also be oval, circular or other closed figures.
Further, when described hollow out window was rectangle, its lateral length was 10mm-30mm, vertical width is 10mm-20mm.
Like this, have vacancy section on the antenna thin layer and just formed a type dipole antenna.Said hollow out window is closed form, along with the frequency of the increase antenna of short-circuited conducting sleeve can be to low frequency deviation, and the whole frequency bandwidth of antenna also can become very wide, finally make antenna performance very stable, be attached on the multiple vehicle glass, big variation can not take place in performance yet.Can carry out the adjustment of frequency through the hollow out window, energy passes through the arm on antenna both sides to aerial radiation.
Further, described RFID chip is that the reception signal frequency is the RFID chip of 860MHz～960MHz.RFID in 860MHz～960MHz frequency range technology, it is far away to have a decipherment distance, dynamically reads advantages such as the ability of information is strong down.
Further, described RFID chip is to be fixed on the antenna thin layer with welding or the fixed mode of the nation ground connection that is electrically connected.Can make that the life-span of electronic tag is longer, and can use under the rugged environment more.
The technical scheme of the utility model is substrate with the ceramic material; Because of the characteristics of the rigid brittle of pottery when receiving that deformation takes place stress, will be fractureed, thereby the antenna thin layer that is printed on the ceramic substrate is destroyed; And make the RFID chip can't be read identification, realize the tamper purpose.Under the anti-demolition electronic tags normal condition of ceramic substrate, it is on glass that label is attached to car, and the whole energy of antenna is gone out through the gap radiation on the metal foil face, is convenient to the identification of read write line.
In addition, the ceramic substrate anti-demolition electronic tags of the utility model is compared with other tamper label, has frequency and regulates well and characteristics such as bandwidth is wideer.

Fig. 2 is the cut-open view of the embodiment 1 of the utility model;
Fig. 3 is the cut-open view of the embodiment 2 of the utility model.
Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
Embodiment 1:
Consult Fig. 1 or shown in Figure 2, the anti-demolition electronic tags of the ceramic substrate of present embodiment comprises:
-ceramic substrate 1, the one side of described ceramic substrate 1 forms antenna thin layer 2 by silver slurry silk-screen.
-antenna thin layer 2, the shape of antenna thin layer 2 are to have vacancy section 3 on the metal foil face, and vacancy section 3 is made up of with 1 the hollow out passage 31 that is communicated with the two the hollow out window 32 of 2 symmetrical distributions.Preferably, the shape of described hollow out window 32 is rectangles.When described hollow out window 32 was rectangle, its lateral length was 10mm-40mm, and vertical width is 10mm-20mm.Like this, have vacancy section 3 on the antenna thin layer 2 and just formed a type dipole antenna.Said hollow out window 32 is closed form, along with the frequency of the increase antenna of short-circuited conducting sleeve can be to low frequency deviation, and the whole frequency bandwidth of antenna also can become very wide, finally make antenna performance very stable, be attached on the multiple vehicle glass, big variation can not take place in performance yet.Can carry out the adjustment of frequency through hollow out window 32, energy passes through the arm on antenna both sides to aerial radiation.
