    Proceedings 2nd IEEE International Conference on Device Intelligence Computing and Communication Technologies Dicct 2024, 2024
    In this work, a simple band-dual notched ultra-wide band (UWB) antenna having the characteristics of monopolar type has been conceptualized by creating creating two rectangular slots (DGS) in the ground plane, then printing an H-shaped strip on the rear portion of the substrate and followed by creating a slot of U-shape in nature in the rectangular radiating element (RE) of the conceptualized antenna for the generation of band-dual notched characteristics 3/4 GHz (WiMAX) and 5.1/6.1 GHz (WLAN) for the co-existence of band-narrow WLAN and UWB system simultaneously. The proposed stricture provides the wide operating UWB bandwidth of 2.46 to 14.69 GHz with 143% fractional bandwidth (FB). The conceptualized antenna demonstrates the appropriate gain in the UWB systems and exhibits the stable radiation pattern (RP) for proper operation in UWB systems.
