UWB antenna with reconfigurable band-notched characteristics using ideal switches

A CPW-fed band-notched Ultra wide band (UWB) antenna that functions as a UWB antenna/ band-notched UWB antenna is proposed. The band-notched function at WiMAX is obtained by etching S-shaped meandered parasitic element within the radiating aperture. Reconfigurability is verified by placing ideal switches across the gaps of the parasitic element. Results show that the proposed antenna with reconfigurable band-notched characteristics operates from 2.5 to 12 GHz.
