A conventional CPW fed circularly polarized slot antenna is presented in this paper. Circular polarization is achieved by using open ended slot at left end of the antenna. The 3-dB axial ratio bandwidth (ARBW) of 700 MHz is achieved in useful range of frequency, relative to 5.5 GHz center frequency. The proposed antenna is circularly polarized in frequency range of 5.1-5.8GHz band used for WLAN/WiMAX applications. The proposed antenna have good bandwidth of 7GHz or 7000 MHz bandwidth by using a simple circular cut in right hand ground plane. This simple circular cut in the ground plane makes the impedance bandwidth is larger than the basic designed antenna. The size of antenna is 50×50×0.8mm3. The impedance bandwidth of 7000 MHz (2.0-9.0 GHz) has been achieved, which is about 127% of relative center frequency. © 2016 IEEE.
