The paper presents a novel wideband circularly polarized antenna for wireless applications. The circularly polarized antenna consists of four printed dipole elements and the feeding network based on sequential rotation technique. This proposed antenna at 5.8 GHz with a wideband of 36.3%, an axial-ratio 3 dB bandwidths of 22,4%, and a maximum gain of 9.8 dBi. A prototype with a dimension of 50×50×22 mm3 has been fabricated and measured. The measurements agree with the simulation results. The proposed antenna is suitable for devices operating in IEEE 802.11 ac Wi-Fi, WLAN, WiMAX, and industrial scientific medical frequency band.
