re. DGS (defected ground structures) may reduce MC by a level of 55 dB [5], resonator antennas having a dielectric may reduce MC by a level of 25 dB [6], CSRRs (corresponding split-ring resonators) may reduce MC by a level of 22 dB [7], lines of neutralization can reduce MC by a level of 23 dB [8-9], a slot element may reduce MC up to 22 dB [10], configurable antennas may decrease MC by a level of 47 dB [11], EBG (electromagnetic band gap) may reduce MC by a level of 53.7 dB [12], designed metamaterial may lower MC by a level of 42 dB [13], a decoupling network may decrease MC by a level of 32 dB [14]. DGS and EBG have been both effective methods for decreasing MC. For all meta surfaces, some meta surface innovations include the realization for different polarization-independent properties. UWB is a particularly desirable technology in a large no of applications, such as imaging systems, short-range radar, and wireless broadband applications [1-2], due to its high data rate, low power, and low cost. However, despite these benefits, UWB technology is plagued with transmission dif- ficulties such as multipath fading. MIMO is viewed as a key to increasing channel capacity and lowering multipath fading in UWB systems without the requirement for more power [3-6]. More focus has been given to the development of a small 4-Port 5G Wireless Communication System in Healthcare Informatics multi-input multiple-output antenna suitable for portable IoT devices. However, difficulties such as common coupling between nearby antenna parts develop when numerous antenna components are mounted on a receiving terminal in a compact space [7]. As a result, numerous novel techniques and procedures are recommended in literature to overcome this disadvantage while maintaining the overall size related to MIMO, using parasitic elements among antenna mounted substrates on both sides, that produce insertion losses of less than 20 dB in the band of operational fre- quency [8], and to reduce the mutual coupling impact, an arc-shaped defected gro
