Four-port multiple-input multiple-output (MIMO) antenna with defected ground structure (DGS) is investigated. In this study proposed design performs operations at diverse frequencies (1.8GHz NB-IoT band, 2.4GHz ISM band, 3.1GHz sub 6 GHz, Wi-Max, and 4.8GHz 5G connectivity band). The antenna is excited by a microstrip transmission line. The proposed MIMO antenna occupies a compact area of 20cm*15cm with isolation of less than -15dB among all ports. Radiation characteristics such as s parameters return loss, and bandwidth is also taken. MIMO performance metrics in terms of Envelop correlation coefficient (ECC) diversity gain (DG) total active reflection coefficient (TARC) and mean effective gain (MEG) are also taken for satisfactory diversity performance.
