A wideband circularly polarized (CP) planar inverted-F antenna (PIFA) is proposed and designed using reactive impedance surface (RIS) for mobile communication. PIFA with RIS is used for CP radiation, size reduction and wideband of the proposed CP-PIFA. It is a different technique for improving the various performance parameters of the antenna, that is, narrow bandwidth, size reduction, and the axial ratio (AR). The structure of circular polarized PIFA is designed, analyzed, geometrically optimized, and implementation of the antenna to operate at 2.4 GHz WLAN bands. Finally, a proposed CP-PIFA is analyzed and simulated using full 3D electromagnetic high-frequency structure simulator (HFSS). The measured impedance bandwidth of designing an antenna (S11) 10-dB is 1399 MHz (1.542-2.943 GHz) 58.29\%, simulated 3-dB axial ratio bandwidth is 870 MHz (1.639-2.50 GHz) 36.25\%, measured voltage standing wave ratio (VSWR) is 1.02 and the realized gain is 8.1 dB for the 2.4 GHz WLAN bands
