Abstract :
In this paper, an aperture coupled circularly polarized microstrip antenna was presented for RFID applications. It shows good impedance and radiation characteristics over 2.35 GHz to 2.55 GHz: gain is more than 9.0 dBic; return loss is less than -13 dB. The prototype is compact, light, simple, and low cost, it is suitable to use for RFID as the reader antenna
