Abstract :
A planar micro strip-fed tab monopole antenna is designed and presented for ultra wideband (UWB) wireless communications applications. The impedance bandwidth of the antenna is improved by adding slit in one side of the monopole, introducing a tapered transition between the monopole and the feed line, and adding two-step staircase notch in the ground plane. The proposed antenna has a small size of 16 x 19 mm, and provides an ultra wide bandwidth from 2.8 to 28 GHz with low VSWR level and good radiation characteristics to satisfy the requirements of the current and future wireless communications systems.
