Abstract
In this paper, a ultra wide band (UWB) multiple input multiple output (MIMO) antenna has been proposed with high isolation and low correlation, which is capable of rejecting IEEE 802.11ac communications (5.1–5.95 GHz). To obtain high isolation, the antenna elements are placed orthogonal to each other. A T-shaped slot is etched in the monopole to improve the wideband characteristics and also to improve the isolation. The proposed antenna covers the frequency range from 3.1 to 8.6 GHz at −10 dB with a bandwidth of 5.5 GHz. The fractional bandwidth obtained is 94%. The isolation obtained is greater than 17 dB. The envelope correlation coefficient of the proposed dual port UWB MIMO antenna is 60% better than the antennas reported in literature.
