In this research paper, a simple design of an ultra-wideband (UWB) multi-input multi-output (MIMO) antenna with low envelope correlation coefficient (ECC), high isolation, enhanced gain, radiation efficiency and reconfigurable band notching functionality is proposed. Two symmetrical slots are carefully integrated into the partial ground plane of the conventional monopole to provide a notched band at 5.8GHz for the WLAN system. This notching method is simple and does not endure negative effect performance or any design complexity. The notched band is then controlled using PIN diodes. A complete biasing circuit is integrated on the same partial ground plane to bias the PIN diodes in forward and reverse directions. To reduce the complexity of the design that may be increased due to the reconfiguration circuit, isolation enhancement is accomplished by orthogonal placement of the elements rather than using any additional decoupling structures. A prototype of the MIMO UWB structure is fabricated and its performance parameters are experimentally tested. The captivating agreement between simulation and measurement demonstrates that the proposed antenna system is a good candidate for UWB applications with an operating band extending from 3 to 11GHz, notch-band reconfiguration freedom, and isolation of more than 20dB.
