摘要：

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.
