A Ultra-wideband(UWB) multiple input multiple output antenna with a compact size of 22 × 36 mm2 at frequency range 3.1-10.6 GHz to overturn the frequency 5.15-5.85 GHz and 3.3-3.8 GHz interfering with WLAN and WIMAX systems is designed for medical applications. The UWB MIMO antenna consists of two triangular monopole antenna elements and a T-shaped ground stub. A vertical slot is cut on the middle of the T-shaped ground stub to reduce the mutual coupling. Also it consists of two strips on the ground plane to suppress the WIMAX & WLANS systems creating a notched band frequency. Measurements are used to study the antenna performance in rapports of impedance matching,isolation between the two input ports,radiation pattern,antenna gain,surface current distribution and envelope correlation coefficient(ECC),total active reflection coefficient(TARC). Outcomes show that the antenna can function from 3.1 to additional 11 GHz with a notched band in 5.15–5.85 GHz and 3.3-3.8 GHz. The mutual coupling observed is less than −15 dB with ECC less than 0.1. © 2016,International Journal of Pharmacy and Technology. All rights reserved.
