Problems solved by technology

Therefore, ceramic electronic tags are widely used as vehicle electronic tags in intelligent traffic management. However, due to the high dielectric constant of the ceramic substrate and the large tangent loss, the Q value of the antenna is too high and the bandwidth is too narrow, which makes the tag useless. certain limitations

Abstract

The invention relates to the field of radio frequency identification (RFID), and provides an ultra-wide frequency band electronic tag. The tag comprises an antenna, a chip and a substrate, wherein the substrate is arranged in a rectangular shape for containing the antenna and the chip. A short circuit ring of the ultra-wide frequency band electronic tag can conveniently regulate the impedance of the antenna, and a special design loaded on a top end can greatly increase the bandwidth of the antenna. When the ultra-wide frequency band electronic tag is used, the chip is fixed on a base material through a solidification function, and the chip and the base material are formed into a whole. Through the structure and the combination of the structure, the ultra-wide frequency band electronic tag which exhibits long read-write distance and is suitable for various occasions is realized.

Description

Technical field: [0001] The invention relates to an ultra-wideband electronic tag, which belongs to the technical field of microwave communication and is suitable for radio frequency identification within the frequency range of 800MHz to 1200MHz Background technique: [0002] With the development of RFID in recent years, electronic tags have been widely used in many fields such as logistics, retail and transportation, which have effectively improved management efficiency and greatly saved labor costs. In intelligent traffic management, electronic tags are required to be non-detachable and unique. Ceramic materials have excellent electrical insulation, high thermal conductivity, high temperature resistance, etc., and are anti-disassembly due to fragility. Therefore, ceramic electronic tags are widely used as vehicle electronic tags in intelligent traffic management. However, due to the high dielectric constant of the ceramic substrate and the large tangent loss, the Q value o...
