Orthogonal Bird Shaped Multiband MIMO Antenna for 5G Technology with High Isolation and Efficiency

In this paper, an orthogonal MIMO (multipleinput multiple-output) bird shaped antenna providing high efficiency and high isolation for 5G technology has been presented which has total number of four elements and each element is constructed on each edge of the Rogers RT5880 substrate. The substrate is designed with a width and length of 32 mm. The patches are constructed orthogonal to one another and on the top and side edges, more patches are added in order to get high efficiency and high isolation so that the antenna looks like the shape of a bird. This MIMO antenna acts a multiband antenna as its four operating bands lie between range 35-65 GHz. Its parameters that is return loss (S11) is working below - 10 dB and isolation (S21) is working below -25 dB which makes its performance efficient.
