A hexagonal shaped six‐port multiple‐input‐multiple‐output (MIMO) antenna array comprising of six printed circular monopole antennas with wideband characteristics is presented. Based on the measured data, −10 dB impedance bandwidth of the antenna is found to be from 3.44 GHz to 4.68 GHz. The isolation between the adjacent antenna elements is enhanced by self‐cancelation of the induced near field currents by printing a microstrip neutralization line between them. Isolation among antenna elements are greater than 15 dB with an inter‐element spacing of 0.076 times the free space wavelength at 3.44 GHz. The maximum gain of the antenna is noted to be 5.1 dBi with an envelope correlation coefficient ≤ 0.4 and channel capacity loss ≤0.0328 bits/S/Hz in its entire operating bandwidth.
