Design of Circular Disc Monopole Antenna for UWB Application
Abstract
A new proposed circular disc monopole (CDM) antenna is designed for ultra-wideband (UWB) application. The dielectric substrate is used to print the antenna which is fed by 50 Ω CPW on the same substrate side. A stub is introduced across the feed line for improving the performances. In addition, the bandwidth (BW) is enhanced using modified ground plane. The simulated outcome shows that the antenna can give an impedance bandwidth of 2.58–12 GHz having reflection coefficient less than −10 dB. Also, the voltage standing wave ratio (VSWR) is less than 2 and the peak gain antenna is up to 4.5 dBi. A fine conformity is obtained between the simulation and the experiment.
