R.SambaSiva Nayak Nayeemuddin Mohammad B.Satyanarayana MD.Javeed Ahammed 01 3 Now a days antennas plays a major role in communications where its demand is gettingincreased to feed the needs in this paper the basic Multiple Input Multiple Output MIMO antenna isdesigned which is of 8 matrix sizes for 5G devices which are high in range and having higher bandwidthThese antennas are of size occupies 3 x 4 mm2 each which is implanted on top most layer of substrate platein Hshaped rotated Patch form Where the total size of substrate we take is of 312 x 312 x 157 mm3 sizewith dielectric constant of size 22 We place total 8 MIMO antennas in substrates top layer and thesubstrates bottom is a ground plane where this ground plane is of Electromagnetic Band Gap EBG designonly for obtaining efficiency and gain enhanced For avoiding spurious radiation if any we feed outsubstrate from the bottom layer through vias These kinds of antennas have resonation at 27 GHZ withbandwidth of 6DB In the whole band width of antennas attained gain is of more than 7 dB that has a highrange 8dB Similarly the efficiency we obtained in these antennas is about 65 than the highest of 93CST microwave design tools are used for these antennas design and the simulation results have given thebetter performance of the MIMO antennas which makes them suitable of 5G technology Copyright (c) World Journal of Pharmaceutical Seiences.
