Summary:a compact MIMO antenna is designed to work at 28GHz and used for 5G applications. In this paper, different isolation techniques were designed and simulated to reduce the effect of the mutual such as coupling defected ground structure (DGS), slab parasitic element place on the top of the substrate between the radiating elements and electromagnetic bandgap structure (EBGs) that works as stop band filter to null out the effect of surface waves. The antenna is physically compacted to small dimensions of 10.235x 9.0187x1.149 mm 3 . In this paper the concentration is mainly about the performance of decoupling techniques to remove the effect of mutual coupling (MC) for closer radiating antenna elements, where they exhibit about 5dB as a minimum difference between the evaluation of mutual coupling without and with the use of suppression decoupling techniques. The MC is reduced from 13dB to 18 dB and 20 dB. In this paper the envelop correlation coefficient (ECC), Diversity gain (DG) are also evaluated and results in less than 10- 5 for ECC, and 10 for DG, which are more suitable for the design.
