Circularly polarized Fractal patch antennas at two frequency ranges are to be resonated in this paper. This fractal antenna is performed better by using probe feeding technique. Existing method is resonate at 3.4GHz and proposed method resonating at 2.5 and 3.4GHz frequency ranges. Ground dimensions are 40mm x40mm and substrate dimensions are 26mm x 26mm, and substrate material is RT/Duriod5880. The proposed method involves unit cell structure with a size of 10mm x 10mm. This Paper enhances the frequency ranges and improves the gain and better return loss. These range of frequency ranges mostly useful for Wi-max applications. All Parameters are simulated by using HFSS software.
