In this communication, a compact (30×30×1.6 mm3) microstrip line fed loaded quad-port and T-shaped wideband MIMO (Multiple-Input Multiple-Output) antenna for K band (18-27GHz) application is introduced. Here three simulated antennas (Antenna-1, Antenna-2 and Antenna-3) are analytically inspected in expressions of simulated gain, return loss (|S11|, |S22|, |S33| and |S44|), total active reflection coefficient (TARC), isolation (mutual coupling), diversity gain (DG), radiation efficiency, radiation pattern and envelope correlation coefficient (ECC). Antenna 3 disclaimers have been elevated for chosen antenna considerations and performance. The proposed antenna has |S11|, |S22|, |S33| and |S44| not more than -10 dB and the percentage impedance bandwidth is 19.54% (19.48-23.70GHz), 18.74% (19.58-23.63), 16.31% (19.54-23.01GHz) and 18.27% (19.39-23.29GHz) at ports 1, 2, 3 and 4 respectively. Simulated isolation is < -15 dB, ECC obtained between ports 1-2, 1-3 and 1-4 is not more than 0.06, DG originated among the ports 1-2, 1-3 and 1-4 is in the range of 9.969-9.999 (dB), TARC < 0 dB and radiation efficiency of 60% is obtained. The proposed design model of antenna has been analyzed with HFSS simulation tool by ANSOFT version 13.Keywords
