Abstract

In this article, a 4 x 4 element wide band (UWB) multiple-input multiple-output (MIMO) antenna is proposed. The total size of the proposed antenna is 40 x 40 x 1.6 mm3. The antenna elements are placed orthogonal to each other. A CSRR shape like elliptical slot is etched on the radiating element to achieve dual band notch characteristics at WiMAX 4.8 GHz regions. The proposed antenna operates from 4.8 to 9.2 GHz, which exhibits a reflection coefficient of S11< -10 dB and has isolation better than 20 dB. Envelope correlation coefficient (ECC) mutual coupling performance of the presented antenna which is around 0.01 to 0.02 at the operating bands.
