Abstract: The multi-port MIMO antenna system is designed for ultra-wideband applications, featuring a configuration of monopole radiating elements that provide spatial diversity. These elements are oriented vertically and arranged orthogonally to form a three-dimensional non-planar structure. A conductive vertical extension is capactively attached to each radiator and ground plane portion, interconnected by a fan shaped common ground plane. This design ensures a uniform electrical ground reference and suppresses surface currents, achieving isolation between antenna ports. The system is suitable for a frequency range from approximately 3.16 GHz to 13.36 GHz, with isolation greater than 20 dB and an Envelope Correlation Coefficient of less than 0.002. Fig. 1
