The circularly polarized microstrip antenna has been of great importance in WLAN applications. A circularly polarized slotted circular patch antenna with co-axial feed geometry has been designed to meet the requirements. The antenna designed has been slotted at several locations to make it radiate circularly polarized radiation. Two metallic cylindrical vias have been inserted near the two diametric ends of the slot to improve the realized gain of the antenna. The antenna structure is resonating at 6.4 GHz with 3dB axial ratio bandwidth of 200MHz and gain of 9.8dB has been observed.
