Design of a Miniaturized Polygonal RFID Tag Antenna

摘要

In order to meet the requirements of miniaturization of RFID tag antenna, this paper proposes a design scheme of polygonal ring dipole tag antenna based on the bent arm structure. Parameter analysis is carried out to study the influence of polygon structure on antenna size and input impedance. The antenna has characteristics of simple fabrication, small size and low sensitivity to environment, and has potential application value in RFID systems.
