Radio frequency identification tag device and packaging box with same

Abstract

The invention relates to a radio frequency identification tag device comprising a cavity, a radio frequency identification tag and a tag antenna, wherein the cavity is used for accommodating articles and conducting electricity; the radio frequency identification tag is arranged in the cavity; the tag antenna is arranged in the cavity and is electrically connected with the radio frequency identification tag; and one dipole arm of the tag antenna, which is a dipole antenna, is electrically connected to the inner surface of the cavity, while the other dipole arm of the tag antenna is suspended in midair. The invention also relates to a packaging box with the radio frequency identification tag device. The radio frequency identification tag device and the packaging box have the beneficial effect that the radio frequency identification tag device can be read in all directions in a metal cavity.

Description

Technical field [0001] The invention relates to the field of radio frequency identification (RFID), and more specifically, to a radio frequency identification tag device and its packaging box. Background technique [0002] Radio Frequency Identification (RFID), especially UHF RFID (UHF RFID) is a long-distance automatic identification technology that uses microwave radio frequency to read tag information. Compared with traditional barcode technology, UHF radio frequency identification technology has the advantages of long reading distance, fast reading rate, strong multi-tag processing ability, long data storage time, large data capacity, no contact, and unique TID (tag identification code) It has become an important part of the Internet of Things technology and has been widely used in logistics and transportation. In a considerable part of UHF radio frequency identification applications, it is necessary to stick radio frequency identification labels inside metal or metal-pl...
