Miniaturization Design of the 5.8GHz RFID Antenna Based on Metamaterial

Abstract:

In this paper we designed a 5.8GHZ microstrip antenna whose relative bandwidth is 3.77% and return loss is-36.941dB. It meets the needs of RFID systems.Besides, the resonant frequency of the antennas is reduced to 5.2GHZ, after adding the “I” ring resonator. Also, the paper shows that the other performance of the antenna still meet the RFID system requirements. It is 47.1% of the original size after adjusting the resonant frequency of the antenna to 5. 8GHz.
