N2 - Modern portable devices provide many features in a single device - this demands high channel capacity for faster data transmission. This paper communicates the two-element multiple-input and multiple-output (MIMO) antenna systems operating in ultrawideband (UWB) characteristics. The antenna elements' less than quarter wavelength separation leads to strong mutual coupling. The projected design improves the isolation using parasitic elements loaded on the radiating plane and slots on the ground plane. The inverted T-shaped stubs creates an alternate current channel and slots disturbs the uniform current distribution and neutralize the coupling effect. The overall dimension of the design is 0.2λ×0.3λ×0.02λ. This improved structure has an S11 of 4.9 GHz to 17.4 GHz, with S11 being less than -10 dB and isolation of more than 20 dB over the operating frequency range. Further, MIMO diversity parameters exhibit ECC<0.005, DG ≈ 10 dB, MEG<-6 dB, TARC<-10 dB, CCL<0.2 bps/Hz, and ME<0 dB, and the outcome guarantees that the projected MIMO design is well suitable for wireless communication applications.
