Abstract
The invention discloses a passive ultrahigh-frequency electronic-label structure used for an automobile. The structure includes a base material, a tag antenna structure and an ultrahigh-frequency radio frequency identification chip. The tag antenna structure is printed on the base material. The ultrahigh-frequency radio frequency identification chip is welded on a feed port of the tag antenna structure through a welding technology. The tag antenna structure includes a first substructure segment and a second substructure segment. The first substructure segment has a structure of Chinese character 'Shan' which is rotated anticlockwise for 90 degrees, that is, the middle of the first substructure segment is a bump and the two ends of the bump are connected with transition segments respectively. The transition segments are connected with extension segments vertical to the transition segments. The second substructure segment has a structure of Chinese character 'Shan' which is rotated clockwise for 90 degrees. The second substructure segment is symmetrical with the first substructure segment. The passive ultrahigh-frequency electronic-label structure used for the automobile has the characteristics of broadband and long-distance identification and capable of satisfying vehicle-operating long-distance automatic identification.

Background technology
At present, passive ultra-high frequency technology is widely used in logistics and warehousing management, intelligent parking lot management, product false proof detects, the fields such as vehicle management, particularly in vehicle management application, due to the complexity of vehicle operating environment, conventionally require RFID label dress to be attached on shield glass, therefore very high to label design performance requirement, this just needs the special RFID label for the complicated running environment design specialized of vehicle, just can meet the reliable recognition management of rfid system to vehicle.
Although applied electronic tag can play certain management role in existing passive ultra-high frequency radio-frequency (RF) identification vehicle management system, but its wideband is narrow, gain is less, decipherment distance is near, can not meet completely rfid system under vehicle operating complex environment to the remote reliable recognition of RFID label.
Summary of the invention
The object of this invention is to provide a kind of automobile passive ultra-high frequency RFID Electronic Tag Structure.
Although what the present invention solved is that in existing passive ultra-high frequency radio-frequency (RF) identification vehicle management system, applied electronic tag can play certain management role, but its wideband is narrow, gain is less, decipherment distance is near, can not meet rfid system problem to the remote reliable recognition of RFID label under vehicle operating complex environment completely.
The technical scheme that the present invention solves its technical matters employing is: the present invention includes base material, tag antenna structure, ultrahigh frequency radio frequency identification chip, tag antenna structure is printed on base material, and ultrahigh frequency radio frequency identification chip is welded on the feed port of tag antenna structure by solder technology.Described tag antenna structure comprises the first minor structure section and the second minor structure section; Described the first minor structure section is to be rotated counterclockwise " mountain " word structure of 90 °, and the centre of the first minor structure is a projection, and the two ends of projection connect transition section, connect perpendicular extension on transition section; The second described minor structure section is " mountain " word structure, the second minor structure section and the first minor structure section symmetry of 90 ° of turning clockwise.
Round-corner transition between one end of described projection and transition section, right angle transition between the other end and transition section.
Described base material is the base material of ceramic material.
Described substrate sizes is 86 mm × 54 mm × 0.65mm or other reasonable size specification.
The invention has the beneficial effects as follows: 1, passive ultra-high frequency label antenna of the present invention, there is the feature of broadband and high-gain, can form the label that is operated in 902-928MHz frequency range optimum impedance coupling.
2, adopt the electronic tag dielectric loss of ceramic material little, high frequency characteristics is good, and antenna performance is stable, highly sensitive.
3, vehicle has remote evident characteristics by RFID tag.Be 1W at read write line power, reading and writing device antenna gain is that 12dBi, vehicle move under highway complex environment, the vehicle of the present invention RFID tag decipherment distance that rfid system is attached on shield glass dress is greater than 15 meters, and for common vehicle electronic tag, under same system environments, decipherment distance reaches 10 meters of left and right only.
