antennas, in particular, are highly promising for UWB wireless communication because of their advantages of compactness, high bandwidth, and low cost [2; 3]. The first step in realizing the UWB spectrum is to create a standard rectangular or circular monopole antenna. Adjusting a monopole antenna's radiating and ground plane structures affects the transmission line characteristics and disrupts the uniform current distribution, resulting in impedance matching over the intended frequency of operation. Various antenna configurations are described in the literature to achieve impedance matching over the UWB band. In [4], the authors present an inverted L-shape with a microstrip feedline and a square slot antenna. The geometrical adjustment of the feedline and slot contributes to achieving an impedance bandwidth of 3.5 to 9.5 GHz. The combination of different geometrical cylinders with coplanar waveguide (CPW) staircase slot ground structure UWB monopole antenna is demonstrated in [5]. The rectangular radiator with arc shape truncation at the lower corner and CPW arrangement used to realize the frequency from 3.1-11.8 GHz is presented in [6]. For the UWB spectrum, an arc-shaped radiator with a lower ground plane composed of parasitic components is illustrated in [7; 8]. The extended UWB band monopole antenna consisting of a spline-enhanced based radiator and defected ground structure (DGS) is presented in [9]. Although the UWB system has numerous benefits, including wide bandwidth, it interferes with the existing narrow bands. Conventional antenna design techniques for band rejection characteristics are generally centered on employing a half- or quarter-wavelength filter arrangement. Several other techniques for eliminating single or multiple frequency bands have been reported in the literature, including different structured parasitic elements loading on the radiator and ground plane, metamaterial loading, embedding the filter and antenna, and combining two or more notching techniques as a hybrid approach [10]. The Sprocket gear wheel-shaped radiating patch defected by the arc and rectangular slots to accomplish two frequency band notches is presented in [11]. The fractal UWB antenna in [12] comprises an inverted S and a pair of L-shaped slots and stubs on the radiator to accomplish WLAN and X-band frequency notching. In [13], the WiMAX and WLAN frequency bands are filtered utilizing S and inverted U structure slots on the hexagonal patch and ground plane. The authors in [14] illustrate the WLAN and X-band notching characteristics of the circular ring UWB antenna. Band notching is accomplished using parasitic elements on the radiator and a capacitively-loaded loop on the ground plane. The design and positioning of the notching element on the radiator or ground plane primarily influence the desired frequency of notching. The need for good reproducibility, i.e., wireless links susceptible to multipath fading and higher data rate, is rising proportionally to the progress of wireless communication technology. The portable gadgets are outfitted with diverse approaches to meet the requirement without extending either the spectrum or the transmission power. The compactness features of devices confine the placement and floor planning of the sub-components. Furthermore, putting several antennas in a small area will cause strong mutual coupling between the antennas. In the literature, a large number of band-notched UWB MIMO antennas have already been documented. In such antenna systems, isolation is enhanced by utilizing different approaches, such as defected ground structure (DGS), decoupling networks, neutralization line (NL), metamaterial loading onto the ground and radiator, incorporating filters, and a combination of two or more decoupling structures as hybrid techniques, as reported in [15; 16]. In [17], a two-port UWB fractal antenna with the dimensions of 26 \(\times\) 35 mm\({}^{2}\) operating from 2-10.6 GHz was demonstrated.
