The ultrawideband (UWB) planar antenna is designed as a circular metallic patch fed by a coplanar waveguide (CPW). This antenna provides the impedance bandwidth of the wideband response from 2.5 to 12 GHz. To achieve the notched characteristics at desirable frequencies, the electric ring resonator (ERR) incorporated into the CPW feedline is proposed for use in the planar configuration of the UWB antenna...
The ultra-wideband (UWB) monopole antenna is designed as the circular patch fed by a coplanar waveguide (CPW). To achieve the notched characteristics at desired frequencies, the electric ring resonator (ERR) incorporated into the CPW feed line is used. The notched frequency band is controlled by dimensions of the ERR structure. The single-notched band is obtained by placing a single-mode ERR beneath...
