In modern wireless communication, the enhancement of 5G wireless applications vigorously increases the growth for gaining in MIMO (Multiple Input Multiple Output) technologies. In the conventional method, the MIMO antenna is not efficient by having 5GHz with a resulting 75 % and the interference is difficult to exclude. The proposed MIMO antenna design is modeled by four truncated circular patches of radius 9.35 mm at the top layer with a dual partial ground of 10 mm 60 mm at the bottom to provide better performance. The FR-4 epoxy substrate is counted with the dimensions of 70 mm 60 mm 1.6 mm. An impedance bandwidth ranging from 1.7 GHz to 12.4 GHz with 10 dB return loss and isolation of 15 dB is observed for all four planar antennas. The defective ground sketch in the planar plane is functioned by several slots, metamaterials, etc. achieved by the band-notch. The proposed system is obtained to improvise the performance by HFSS simulated results for operating frequency by MIMO antenna as 1.7 GHz to 12.4 GHz. It provides the directivity as 4.6 with a relative permittivity of 4.4 and isolation as 15 dB. Further, the gain of 5.7 dB with an efficiency of 87.95 % has been achieved by the insertion of the Electromagnetic Band Gap (EBG) structure between the two partial ground planes at the bottom. Hence the proposed EBG is proven better than the conventional method SISO antenna in all performance aspects through the MIMO antenna in 5G applications. |
