Compact Fractal Shaped MIMO Antenna for Portable UWB Applications

In this study,a UWB multiple-input-multiple-output (MIMO) antenna for different portable and ultra wide band application is presented. The designed antenna consists of two rectangular shapes of radiating elements and two multiple ports. The ground plane has been designed with a T-shaped stub with fractal implementation to minimize the mutual coupling effect. The dimension of the substrate taken is of 22x36x1.6mm ³ . Reflection coefficient (S11) denotes the bandwidth of the antenna which is less than -10dB and ranges from 2.56 GHz to 19.74 GHz. Transmission coefficient (S21) for mutual coupling which is less than -15 dB.
