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; The appearance 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 appearance is more accurate.
The utility model content
Based on the above-mentioned deficiency of saying, the utility model is invented a kind of ceramic anti-demolition electronic tags through groping for a long time, and its speed height of not only making an inventory accurately, and has 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 the slits that has hollow out on the metal foil face;
-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 silver-colored thin layer that the printed antenna thin layer is formed by silver slurry silk-screen on the described ceramic substrate.
Further, the shape in described slit is " worker " font.Said slit is " worker " shape, thus up and down with about all become symmetry shape, also be more uniform so be radiated airborne shape, thereby be convenient to the identification of read write line.
Further, the length of 2 transverse slots in the slit of described " worker " font is 10mm-60mm, the length in vertical slit is 5mm-40mm.
Further, the spacing width in described slit is 0.5mm-5mm.
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.

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 the slits 3 that have hollow out on the metal foil face of large-area bulk, and the shape in the preferred slit 3 of present embodiment is " worker " fonts.Said slit is " worker " shape, thus up and down with about all become symmetry shape, also be more uniform so be radiated airborne shape, thereby be convenient to the identification of read write line.The spacing width in described slit 3 is 0.5mm-5mm.The length of 2 transverse slots 31 in the slit 3 of described " worker " font is 10mm-60mm, and the length in vertical slit 32 is 5mm-40mm;
-RFID chip 4, the ground connection that is electrically connected is fixed on the antenna thin layer 2.RFID chip 4 is that to receive signal frequency be the RFID chip of 860MHz～960MHz, the RFID technology in 860MHz～960MHz frequency range, and it is far away to have a decipherment distance, dynamically reads advantages such as the ability of information is strong down.And RFID chip 4 is to be fixed on the antenna thin layer 2 with welding or the fixed mode of the nation ground connection that is electrically connected, and can make that the life-span of electronic tag is longer, and can be in rugged environment use down more;
