A folded dipole antenna for RFID tag

Abstract

In this paper we designed a folded dipole antenna for RFID tag, the influence of the antenna's geometrical parameter to the antenna's resonant frequency and impedance is presented, The simulation results demonstrate that the changing geometrical parameter of the folded dipole antenna is an effect method to adjust the input impedance and resonant frequency, and it is better than half wave dipole antenna in adjustability, it's suitable for the application of RFID tag antenna.
