Abstract: 5G is the proposed next telecommunication standard beyond the current 4G/IMT-Advance standards, operating from 2GHz-8GHz.Antenna fabrication with reduced mutual coupling is the major challenges. Rectangular Fractal slots are used to enhance bandwidth without any matching element and for good radiation pattern. In this paper we have designed dual element Multiband MIMO antenna for 5G application which operates in 3.1GHz,3.6GHZ and 3.9GHz with reduced mutual coupling. To analyze mutual coupling, two antennas are placed at a distance of 0.125λ.Various techniques to reduce mutual coupling like Electromagnetic Band Gap(EBG),Meander line, Defective Ground Structure(DGS)are implemented and out of which DGS has better isolation. An isolation of -59dB has been achieved with the DGS structure relative to -29dB without the DGS.
Keywords: MIMO Antenna, Mutua Coupling, Electromagnetic and Gap(EBG), Meander line, Defective Ground Structure(DGS), Hi gh Frequency Structure Simulator(HFSS).
