Abstract

The invention discloses a radio frequency identification antenna and a preparation method thereof. According to the radio frequency identification antenna, an antenna pattern is printed and compactedon a fragile paper substrate through light-curable conductive ink; the thickness of the antenna pattern ranges from 3 to 15 microns. The antenna is compact in structure, has excellent performance, andcan be used for making a fragile, anti-tear and anti-transfer electronic label. The radio frequency identification antenna has the advantages of low manufacturing process difficulty, high productionefficiency and high industrial applicability.

Description

technical field [0001] The invention relates to a radio frequency identification antenna and a preparation method thereof. Background technique [0002] In radio frequency identification (RFID) electronic tags, the antenna is the main functional layer, and its purpose is to transmit the maximum energy into and out of the tag chip. The antenna is an electronic circuit designed according to the functions required by radio frequency identification. The production quality of the antenna is a key issue that needs to be controlled in the RFID tag manufacturing process. The most commonly used method is to load metal film (aluminum foil, copper foil) antennas on substrates such as PVC, PI or PET through an etching process, but this method is cumbersome and pollutes seriously. Another way is to use hot-stamping metal foil to directly hot-stamp the antenna on the substrate, without the need for film materials, but the use of hot-stamping technology to make antennas has a low yield r...
