In this paper, the authors present a compact MIMO antenna for Wi-Fi/WiMAX application. The antenna consists of two crescents shaped Radiators placed symmetrically along the ground and are connected by the neutralization line to achieve good impedance matching and low mutual coupling. The compact antenna with a size of 40x90mm is proposed. The antenna works in two operating i.e. lower band range from 3.01GHz to 3.55GHz while upper band range from 5.55GHz to 6.54GHz. The reflection coefficient in both band is achieved below -10dB. Besides, port isolation, envelope correlation coefficient and radiation characteristics are also investigated.
