Abstract
In this paper, a planar microstrip-fed tab monopole antenna is designed and presented for ultra-wideband (UWB) wireless communication applications. The impedance bandwidth of the antenna is enhanced by adding a slit on one side of the monopole, introducing a tapered transition between the monopole and the feed line, and incorporating a two-step staircase notch in the ground plane. The proposed antenna would be printed on an Epoxy FR4 substrate, has a small size of 16×19mm, and provides an ultra-wide bandwidth from 1.2 to 20.8 GHz with a low VSWR level and good radiation characteristics, satisfying the requirements of current and future wireless communications systems.
