Abstract
This article features about an ultra-wideband (UWB)-multiple-input multiple-output (MIMO) antenna that exhibits the potentials of good port isolation and dual-band suppression. The proposed antenna model consists of a unique fractal-shaped radiating patch, a common ground interface leading to the incorporation of an intuitive approach; parasitic inverted neutralization stubs, which is located at the central co-ordinate axis system, protruded vertically, where its extension is twisted with a motive of enhancing the port isolation. In addition to that, contiguous notches are implemented to achieve band-notching at WiMAX (3.35-4.45 GHz) and X-band (9-10 GHz). The total electrical area of UWB MIMO antenna is 0.179(λ0)2 at 2.25 GHz. To rationalize the counterparts of MIMO and band-notching, diversity performance is studied through the electromagnetic (EM) solver and the corresponding circuit analysis is pursued through a electronic design automation (EDA) solver. The prototype has been fabricated, measured, and agreed well with the simulated results. The feasibility of proposed antenna model is considered to be quite optimum, with due consideration of its outcomes from applications point-of-view.
