Description

Linear copper wire antenna radio frequency tag

Technical Field

Background

In the ultrahigh frequency band rf tag, the mainstream technology of the antenna is a graphic antenna. The method refers to that in the ultrahigh frequency band radio frequency tag, each arm length of a radio frequency dipole (symmetrical array) antenna is 1/4 wavelength, and the total length of the antenna is 1/2 wavelength. Taking the frequency band of the radio frequency tag in China as an example, the standard of the frequency band of the radio frequency tag is 915MHz, the wavelength is 327mm, and the theoretical length of the dipole antenna is 1/2 wavelength (namely 163.5 mm). The antenna of the radio frequency tag commonly used in the industry adopts a pattern design technology of reducing the antenna size technology-bending method, namely, the length of the antenna is shortened to 50-80mm, and the antenna is called as a pattern antenna.

However, in the manufacturing process of the conventional pattern antenna of the ultrahigh frequency band radio frequency tag, a PET aluminum plating composite material is adopted, and the PET substrate aluminum foil radio frequency antenna is manufactured through multiple processes of photosensitive material printing, exposure, development, fixation, chemical etching of an aluminum foil, water washing, drying and the like. The defects include:

(1) A large amount of waste liquid and waste water are generated in the manufacturing process, so that the environment is polluted;

(2) The manufacturing process is complex, which results in high cost of the radio frequency tag.

Because the pattern antenna of the traditional ultrahigh frequency band radio frequency tag has the defects, the popularization and the application of the radio frequency technology are influenced.

In addition, in the manufacturing process of the traditional ultrahigh frequency band radio frequency tag antenna, an inductance coil part and a radio frequency chip of the radio frequency tag are bonded on the inductance coil through conductive resin to form a whole, which is called "INLAY" in the industry. The radio frequency tag and the radio frequency antenna part can not be separated, and the radio frequency chip can not be recycled for multiple use. Therefore, the radio frequency tag chip is lost after being used, and the application cost of express RFID tags and aviation luggage tags cannot be reduced.

The above-mentioned drawbacks are worth improving.
