N2 - The device's dependence on wireless communication and the users exponentially increases with time. The technology evolution demands high data rate transmission and is proportional to the bandwidth. The ultrawideband (UWB) technology provides unregulated bandwidth of 7.5 GHz. For data transmission, UWB technology employs short time-domain pulses (ns) and may result in interference. As a result, in order to assess antenna efficacy, UWB antennas must investigate both temporal and frequency domain features. This paper presents designing a UWB and UWB dual-band notch antenna for wireless applications. The projected UWB structure is a combination of a triangle, different width rectangles, and lowered ground plane. The overall dimension of the antenna is 31.5×23.5×1.6 mm3, with an operating frequency from 2.8-11.6 GHz. An L-shape slot is incised on the radiator to improve impedance matching at the higher frequencies by altering the uniform current path. The designed UWB is also exposed to dual-band notching between 3.7-4.4 GHz and 4.8-5.5 GHz frequencies covering C-band and WLAN, WiFi frequency spectrum. Band notching is achieved using to inverted L-shaped slit, one at the right and the other at the left of the radiating plane. The projected designs also investigated time-domain features such as isolation <-35dB, group delay <1ns, and phase response found to be linear across the operational frequency.
