CPW-fed Circularly Polarized Wideband Slotted Antenna for Wireless Applications

Abstract

A compact CPW-fed circularly polarized wideband slotted antenna is presented in this electronic document applicable for satellite and wireless applications. The design has a simple uniplanar configuration because of the use of CPW-fed, and has a asymmetric wide slotted ground plane which causes circular polarization and a zigzag shaped stub protruding inside it cause antenna to cover a wideband range. The proposed antenna is designed and simulated using ANYSS HFSS simulator software. The simulated −10[dB] return loss impedance bandwidth is 101.01 %(2.06 GHz-7.34 GHz) with solution frequency 5.24 GHz. The proposed antenna possesses a good circular polarization with wide axial ratio bandwidth 72 %(2.05 GHz-5.83GHz)
