Abstract

Disclosed are a tag antenna and a tag. The tag antenna comprises an antenna body (1), the antenna body (1) comprises an inductance part (11) and radiation parts (12) symmetrically located on the two sides of the inductance part (11), and the inductance part (11) comprises a feed access line (111) and a plurality of transmission lines (112) connected with the feed access line (111) in parallel. Therefore, the inductance part (11) forms a plurality of closed loops. The tag antenna is provided with a plurality of transmission lines which can form a closed loop with the feed access line, frequency adjustment can be realized by disconnecting one or more transmission lines according to use occasions, the size is not too much larger than that of a single-frequency tag antenna, and the tag antenna conforms to the development trend of miniaturization while the application range is expanded.

Description

technical field [0001] The invention relates to the technical field of electronic tags, in particular to an electronic tag antenna. In addition, the present invention also relates to an electronic tag provided with the tag antenna. Background technique [0002] Electronic label technology is an underlying technology of the Internet of Things, an important source of information acquisition, and is indispensable for the development and improvement of the Internet of Things. Electronic tags can be used in many occasions, such as metal, plastic, carton, clothing, glass, etc. Different back stickers have different effects on label performance. For example, materials with high dielectric constant will make the frequency of the best performance point of the label lower, while materials with low dielectric constant will make the best performance of the label The frequency of the points is high, which makes it often necessary to use tags with different performances in different app...
