A novel circularly polarized dual-band slot antenna for RFID applications
In this paper, a new slot antenna is proposed for dual-band RFID applications. This antenna is designed to covers the frequency of ISM Bands (2.45GHz and 5.80GHz). In this antenna, two squared-slots are used for dual-band characteristic. Furthermore, some perturbations are set on an appropriate location to achieve circular polarization radiation. An L-shaped feed line is used for antenna excitation. The simulations results show that the proposed antenna has good circularly polarized radiations and the 3 dB axial-ratio bandwidth is more than 7.2% and 5.8% for first and second bands respectively. therefor, it is suitable to use for RFID as the reader antenna.
