Design of Flexible RFID Tag Antenna Suitable for Aviation Material Management

In order to reduce the operating costs of airlines, eliminate outdated labor-intensive maintenance, assist in the management of civil aircraft onboard equipment, track and manage aircraft components. Especially for the maintenance and management of bending components on airplanes, this paper designs and studies a flexible RFID tag in the UHF frequency band based on its usage characteristics. The tag antenna adopts a T-shaped matching network structure and bending antenna method, with a size of 64mm*12mm*1mm; The working frequency of the antenna does not change significantly after bending, meeting the reading and writing distance requirements of the entire system. The simulation results show that the working frequency of the RFID antenna is still within the range when bent, and the maximum reading distance is 6.5 meters, which meets the actual working requirements.
