H type and similar H type ultrahigh frequency radio frequency tag

Abstract

The invention provides an H-type and H-like ultrahigh frequency radio frequency tag, which comprises a carrier, a first assembly, a plurality of second assemblies and a chip, and is characterized in that the first assembly is formed on the carrier, and forms an internal field cycle with an electric contact to realize near field communication; each second assembly extends outwards at a preset included angle to be formed on the edges of the two sides of the inner field circulation, each second assembly forms a first outer field circulation and a second outer field circulation so as to form far field communication, and the first outer field circulation and the second outer field circulation are connected; the chip is connected with the electric contact to transmit an electric signal; wherein the electrical signal is transmitted through the infield cycle and the first outfield cycle.

Description

technical field [0001] The invention relates to the technical field of high frequency radio frequency tags, in particular to an H-type and H-like ultra-high frequency radio frequency tag. Background technique [0002] The existing RF antenna design is used for near-field communication and far-field communication. In order to achieve better signal transmission quality, how to make the RF antenna design have the best reading effect and resist electromagnetic interference becomes important. topic. [0003] Aiming at the lack of the existing radio frequency antenna, a new design of radio frequency antenna is proposed to solve the problem of signal attenuation or badness caused by special environments such as metal, water and low temperature. However, although the aforementioned radio frequency antenna solves the interference factors of the external environment, in some application fields that require small size and small area, such as blood bags used to store liquid biological ...
