Abstract This article regards to a compact shaped MIMO antenna array using planar structure for a range of ultra wideband (UWB) frequencies. This configuration comprised of four element system covered within the area of 0.16λo2 (λo being highest operating wavelength). The proposed MIMO antenna structure aimed to achieve adequate bandwidth and acceptable isolation level which consisting of inverted L-shaped elements with partial interconnected ground plane. Final design provides to achieve an impedance bandwidth (S11< -10dB) that covers entire UWB frequency range (3.1-10.6 GHz). A satisfactory isolation among interelements about 19 dB is achieved to the maximum range of UWB. Besides this, envelope correlation coefficient (ECC<0.1) is also attained. The results obtained from the simulation is carried out using Ansoft HFSS (High Frequency Structure Simulator) provides sufficient bandwidth and isolation levels covering almost entire of UWB frequencies.
