Abstract
The utility model discloses an electronic tag, which comprises an antenna substrate, an antenna circuit and a chip. The antenna circuit and the chip are connected with each other and are arranged on the same side surface of the antenna substrate. The other side surface of the antenna substrate, which is opposite to the above side surface with the antenna circuit and the chip, is provided with dark streaklines. The dark streaklines are at an included angle of 15-75 degrees relative to the lateral edges of the antenna substrate. According to the technical scheme of the utility model, the number of the dark streaklines on the electronic tag is less and the standard operation is carried out. In this way, the tag is prevented from being broken off during the assembly period. When the tag is to be disassembled, the tag is broken off along the dark streaklines of the substrate due to the strong viscidity of the double-faced adhesive tape or the glue solution. Then the key part of the ultrahigh-frequency antenna circuit, such as a closed loop, is destroyed by the broken dark streaklines. Therefore, the performance of the antenna circuit of the tag is decreased severely, so as to realize the invalidation of the tag.
Description
Technical field
The utility model relates to the REID field, relates in particular to a kind of electronic tag.
Background technology
In recent years, REID is increasingly extensive in the application of intelligent transportation industry.Electronic tag is used on the various vehicles as an important component part of radio-frequency (RF) identification.Along with improving constantly of ultra-high-frequency passive chip sensitivity, but the decipherment distance of label is also more and more far away, and the ultrahigh frequency label has the advantage on the cost with respect to the active label of microwave frequency band, so the ultra-high-frequency passive system applies is also more and more in the case of intelligent transportation industry.
The vehicle electric label, label is attached to the windshield inboard during application.Vehicle on the market is a lot of at present, and the windshield kind is also a lot, and the dielectric constant range of most glass is between 5～13, and the difference of glass can have influence on the impedance of electronic tag, thereby has influence on the performance of electronic tag.In order to strengthen the adaptability of label on different glass, all can hold the ring of 1～2 sealing on most ultra-high frequency antennas at the chip place, because the existence of closed-loop has reduced the influence degree of different glass to the label impedance, strengthened the versatility of label.
Except the requirement of versatility, the intelligent transportation industry also has very high requirement to the tamper of passive label, after in a single day label is installed on the vehicle windscreen, does not just allow to dismantle privately.Industry realizes for the bad antenna of the main breaking of tamper of label, such as opening various grooves (hole, seam) at ceramic substrate, in case during dismounting, label ruptures along groove (hole, seam); Or open some staggered dark streaklines (broken memory line) anyhow at ceramic substrate, label along dark streakline fracture, falls thereby antenna is destroyed when dismounting.
But at substrate fluting (hole, seam), though realized tamper, bring two problems: the one, because the existence of groove (hole, seam) is not attractive in appearance in appearance, influenced the integrality of label design; The 2nd, the case material of label encapsulation is required very high, in case case material expands or contraction coefficient is big, label is fracture easily in the environment of high temperature or low temperature.And open dark streakline at ceramic substrate, and unreasonable if layout gets, fracture when mounted easily, though perhaps ceramic substrate when dismounting fracture can not have influence on the closed hoop on the label antenna, the performance of label does not have obvious decline.
The utility model content
The technical problems to be solved in the utility model provides a kind of electronic tag, and is not fragile when label is installed, and can destroy key components such as antenna when label is disassembled.
For solving the problems of the technologies described above, a kind of electronic tag of the present utility model, comprise: antenna substrate, antenna circuit and chip, described antenna circuit is connected with chip on the side that all is arranged on described antenna substrate, offer dark streakline in relative another side, the side with described antenna circuit and chip are set of described antenna substrate, the widthwise edge of described dark streakline and described antenna substrate is 15 °～75 ° angle.
Further, offer ring at described antenna circuit, projection and the described antenna circuit ring offered of at least one dark streakline on antenna circuit intersects.
Further, intersect on vertical limit of at least one dark streakline and described antenna substrate.
Further, described dark streakline is 1～6.
Further, the ring of offering on the described antenna circuit is annulus, elliptical ring or polygon ring.
Further, the degree of depth of described dark streakline is 1/4th to 1/3rd of described antenna substrate thickness.
Further, described dark streakline is formed rhombus or triangle.
Further, also comprise housing, described housing is arranged on the side of the described antenna circuit of arranging of described antenna substrate and chip, and described antenna circuit and chip are in described housing.
Further, described antenna circuit adopts the mode of binding or paster to be connected with chip.
In sum, the beneficial effects of the utility model comprise:
(1) electronic tag needs to stick on glass with viscosity strong double faced adhesive tape or liquid glue when mounted, for better fixed labels, need apply certain power to label, anyhow Jiao Cuo dark streakline is because quantity is many, the antenna substrate original physical characteristics changes bigger, the label that when applying power, fractures easily, and label of the present utility model is because dark streakline quantity is few, and can carry out the operation of standard, avoid the installation phase label to be fractureed.
(2) label is when dismounting, because the strong viscosity of double faced adhesive tape or liquid glue, label will be along the dark streakline fracture of substrate, the dark streakline of fracture can destroy the key position on the ultra-high frequency antenna circuit, as the ring of sealing, the performance of the antenna circuit of label will seriously descend, thereby make label lose efficacy.
