Abstract :
The presented paper exhibits a coplanar waveguide (CPW)-fed symmetrical staircase shaped, planar monopole Ultra Wideband (UWB) antenna having dimensions 4030×l.6mm3 with 5GHz WLAN notch band characteristic. The staircase pattern in the radiating patch and the U-shaped slot resonator in the feed line are used to achieve the UWB and notch the 5GHz WLAN band, respectively. The proposed antenna has impedance bandwidth ranging from 2.84GHz-13.9GHz to cover UWB. Interference caused by WLAN band from 5.15GHz-5.35GHz and 5.725GHz-5.825GHz is notched effectively. The proposed antenna has been printed on FR4 substrate with dielectric constant of 4.4 and thickness of 1.6mm. Moreover, the fabricated prototype antenna shows a good agreement between the simulated and measured results.
