An insertion RFID tag, comprising a substrate (6) and an insertion RFID tag antenna provided on the substrate (6), wherein the tag antenna comprises a first antenna (1) and a second antenna (2); the distance between the first antenna (1) and the second antenna (2) can be adjusted in an extendible manner; a dielectric plate (4) is provided on the second antenna (2), a tag chip (5) is provided on the dielectric plate (4), and the tag chip (5) is electrically connected to the antenna; an elongated isolation slot (17) is provided on the first antenna (1); and a frequency raising notch (18) is provided on the second antenna (2) and the first antenna (1). The reading distance of the RFID tag is long, and upon testing, the reading distance thereof can be up to 11-13 m; and the tag can be extended, i.e. the length can be adjusted, and can be used on pair packages with a basically fixed width but an uncertain length, has a great practical value, is good in various antenna performances, small in standing wave ratio, low in return loss and high in gain and is omnidirectional. |
