Abstract

In this study, a new compact Circularly Polarized (CP) antenna is presented. The impedance matching and the radiation characteristics of this proposed structure is studied using method of moment techniques. The proposed antenna is based on L-probe fed with thick air-filled substrate, truncated corners and two L-shaped slits on the patch. The achievable bandwidth of the proposed antenna obtained is 27% (2.14-2.81 GHz) at -10 dB return loss. The radiation pattern of the antenna shows that the antenna radiates in Right Hand Circular Polarization (RHCP) with achieving an Axial Ratio (AR) bandwidth of 4.3% at 3 dB and a maximum gain of 8.7 dBi. The proposed antenna is suitable for the application in Wireless Local Area Network (WLAN) 2.4 GHz frequency band. The details of the proposed design method is presented and discussed.
