Vehicle-identification-oriented passive ultra-high-frequency (UHF) radio frequency identification (RFID) electronic tag structure for

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 ...

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 body and the operating environment to meet the needs of the RFID system in the vehicle. Long-distance and reliable identification of RFID electronic tags in a free-flow operating environment

[0003] At present, although the electronic tags used in passive UHF RFID vehicle management systems can meet some application needs, their narrow bandwidth and short recognition distance cannot fully meet the long-distance reliability of RFID electronic tags in the free-flow environment of vehicles. identify
