Abstract
In this paper, a Coplanar Wave Guide (CPW)-Fed microstrip octagonal patch antenna for RFID Applications is proposed. The studied structure is suitable for 2.45/5.80 GHz applications. The octagonal shape is obtained by making a cut in the four angles of the rectangular microstrip patch antenna; in addition the using of CPW-Fed allows obtaining UWB characteristics in the higher band. The miniaturization in the antenna size for lower band is achieved by introducing an inverted E slot in the radiating element. The proposed antenna is designed on a single and a small substrate board of dimensions 29.5 × 29.5 × 1.6 mm3. The simulated bandwidth of 5.73% (2.37 GHz to 2.51 GHz) and 34.36% (4.70 GHz to 6.65 GHz) is achieved for the lower band and the upper band, respectively. Moreover the miniaturized antenna has a good impedance matching and an enhanced gain. All the simulations were performed in CADFEKO, a Method of Moment (MoM) based solver.
