Dual-Band Dipole Antenna for 2.45 GHz and 5.8 GHz RFID Tag Application
In the last few years, the wireless identification and communications technology has been developing rapidly. Radio Frequency IDentification (RFID) is obtaining a growing interest to wirelessly track and identify objects due to its cheapness and reliability. In this paper, a dual-band dipole antenna for passive Radio Frequency IDentification (RFID) tag application at 2.45GHz and 5.8GHz is designed and optimized using HFSS 13. The proposed antenna is composed of a bent micro-strip patch and a coupled rectangular micro-strip patch. The optimal results of this antenna are obtained by sweeping antenna parameters. Its return losses reach to -18.7732dB and -18.2514dB at 2.45GHz and 5.8GHz, respectively.
