Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency tags, in particular to an ultra-high frequency radio frequency tag. Background Art

[0002] Radio frequency tags are also called electronic tags, transponders, and data carriers; readers are also called readout devices, scanners, readers, communicators, and reader-writers. The electronic tag and the reader realize spatial (contactless) coupling of radio frequency signals through coupling elements; in the coupling channel, energy transfer and data exchange are realized according to the timing relationship. Traditional radio frequency identification tags generally include: a substrate layer, a radio frequency antenna and a chip. The radio frequency antenna is arranged on the substrate layer, and the chip is connected to the radio frequency antenna; the radio frequency antenna includes a small loop coupling antenna and a dipole radiation gain antenna, and the chip is bonded to the small loop coupling antenna through conductive glue. Radio frequency tags have a wide range of uses, and different occasions have different needs.

[0003] The UHF RFID tag disclosed in the announcement number CN209746590U includes a substrate layer, a RFID antenna and an UHF RFID chip; the RFID antenna includes a small ring coupling antenna located in the middle, the small ring coupling antenna is in a "concave" shape with an opening in the middle, and the two sides of the opening are respectively a left pin and a right pin; the opening and the inside of the small ring coupling antenna have two first square metal sheets, an inverted triangular metal sheet and four second square metal sheets are arranged above the UHF RFID chip, one corner of the triangular metal sheet is facing the center of the UHF chip, and the four second square metal sheets are divided into two groups and two in each group. The utility model improves the balance of the chip when it is placed by setting the shape and position of the metal sheet, and can reduce the parasitic capacitance generated between the UHF chip and the RFID antenna, thereby improving the sensitivity consistency of the RFID tag finally produced.

[0004] Although the above patent improves the balance of chip placement by setting the shape and position of the metal sheet, and can reduce the parasitic capacitance generated between the UHF chip and the RF antenna, thereby improving the sensitivity consistency of the RF tags finally produced; however, the device lacks an auxiliary tearing structure, and the UHF RF tag is usually torn off from the substrate layer manually. Without the help of an auxiliary quick structure, the UHF RF tag is easily torn, causing property loss.

[0005] Therefore, it is necessary to invent an ultra-high frequency radio frequency tag to solve the above problems. Utility Model Content
