摘要

This article features about an ultra-wideband (UWB)-multiple-input multipleoutput(MIMO) antenna that exhibits the potentials of good port isolation and dualbandsuppression. The proposed antenna model consists of a unique fractal-shapedradiating patch, a common ground interface leading to the incorporation of an intuitiveapproach; parasitic inverted neutralization stubs, which is located at the centralco-ordinate axis system, protruded vertically, where its extension is twisted with amotive of enhancing the port isolation. In addition to that, contiguous notches areimplemented 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(λ_0)~2 at2.25 GHz. To rationalize the counterparts of MIMO and band-notching, diversity performanceis studied through the electromagnetic (EM) solver and the correspondingcircuit analysis is pursued through a electronic design automation (EDA) solver. Theprototype has been fabricated, measured, and agreed well with the simulated results.The feasibility of proposed antenna model is considered to be quite optimum, withdue consideration of its outcomes from applications point-of-view.
