A new planar ultra wideband (UWB) antenna of dual notching bands is proposed and presented. The antenna has square patch and a defected grounded plane.
To experience dual notching characteristics, a small T-shaped stub is placed in the square slot at the patch and a double U-shaped strip placed beside the feed line.
The speciality of this current antenna is the high rejection level of notch in the stop band.
The measured readings show that the designed notch planar antenna exhibiting wide bandwidth from 3 to 14 GHz and in voltage standing wave ratio with two notch bands of 3.5–4 GHz (WiMAX band) and 5–6 GHz (WLAN band), respectively.
The correlated measured results with simulation of the proposed antenna projecting that the designed antenna is a suitable for UWB applications.
