Problems solved by technology

Especially in the application of RFID vehicle management, such as the electronic annual inspection mark, it is usually required that the RFID tag be pasted on the upper left corner of the front windshield of the car. The performance requirements of the tag design are very high. Generally, the tags designed in the clear environment are difficult to meet the needs of the vehicle operating environment. This requires a special RFID tag designed specifically for the special structure of the vehicle

Embodiment Construction

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like figure 1 As shown, the present invention includes an UHF radio frequency identification chip 1 , a long-distance UHF radio frequency identification tag antenna structure 2 and a substrate 3 . The base material 3 is a base material made of paper material, and the long-distance UHF RFID tag antenna structure 2 is printed on the base material 3 . The UHF RFID chip 1 is welded on the feeding port of the long-distance UHF RFID tag antenna structure 2 by gold wire ball welding technology.

[0018] The long-distance UHF RFID tag antenna structure 2 includes an upper arcuate segment and a lower arcuate segment, and an UHF RFID chip 1 is connected between the tail end of the upper arcuate segment and the tail end of the lower arcuate segment.

[0019] The tail section of the upper arcuate section and the tail section of the lower arcuate sec...

Abstract

The invention discloses a vehicle-identification-oriented passive ultra-high-frequency (UHF) radio frequency identification (RFID) electronic tag structure. The RFID electronic tag structure comprises an UHF RFID chip, a remote UHF RFID tag antenna structure and a paper base material. The remote UHF RFID tag antenna structure is printed on a substrate, and the chip is welded on a feed port of the remote UHF RFID tag antenna structure through a gold wire ball bonding technology. Based on the automobile front windshield surface mounting background environment, the designed paper substrate passive UHF RFID structure has the advantages of broadband and remote recognition properties and capability to meet remote automatic recognition and management functions under the free stream operation environment of automobiles.

Description

technical field [0001] The invention relates to an electronic label, in particular to a passive ultra-high frequency radio frequency identification electronic label structure oriented to vehicle identification. Background technique [0002] At present, long-distance passive RFID technology is widely used in vehicles, logistics, warehousing, and personnel management. Especially in RFID vehicle management applications, such as electronic annual inspection labels, RFID tags are usually required to be attached to the upper left corner of the front windshield of the car. The label design performance requirements are very high. Generally, the labels designed in the clearance environment are difficult to meet the needs of the vehicle operating environment. This requires special RFID tags specially designed for the special structure and operating environment of the vehicle body to meet the requirements of the RFID system in the vehicle. Long-distance and reliable identification of ...
