Abstract:

In this paper, an ultra-wideband (UWB) planar monopole antenna is proposed whose design is quite simple in profile. The anticipated antenna is composed of a rectangle with corner truncation applied on each corner, with the slits on three truncated corners and a rectangular slot in the middle of patch. The simulated results are obtained using HFSS (High Frequency Structure Simulator) and furthermore the antenna is fabricated on RT Roger Duroid 5880 with the substrate dimensions of 30 mm2 and the height is 0.787 mm with relative permittivity of 2.2. To acquire the maximum bandwidth, a comprehensive parametric study has been carried out to optimize the dimensions of an antenna. Both; the simulated and measured results attests that antenna has wide bandwidth, which ranges from 1.65 GHz to 17.6 GHz and 1.65GHz to 14.5GHz (S11<-10) respectively, along with fine characteristics like good gain, stable radiation pattern and consistent impedance matching.
