Reconfigurable 2×1 CPW-Fed Rectangular Slot Antenna Array (RSAA) Based on Graphene for Wireless Communications

This article presents a 2×1 CPW ultra wideband rectangular slot antenna array (UWB-RSAA) with modified circular shape to support high data rate for wireless communications applications. The proposed dimensions are 0.7λ×0.8λo×0.064λo at the resonant frequency 1.8 GHz. It is fabricated on Rogers RO4003 substrate and fed by using coplanar waveguide (CPW). A graphene layer added one side of realize reconfigurability improve gain. acquires -10 dB impedance bandwidth RSAA that extends from 1.7 GHz 2.6 GHz, 3.2 3.8 5.2 7 achieved realized peak gain 7.5 dBi 6.5 0 Volt bias an average 4.5 over operating band.
