Designed for increased speed and capacity, 5G has the potential to significantly expand the way the data will be processed and transported, and will allow a wide range of new use cases, which go far beyond the smartphone, already targeted by the 3G and 4G technologies. The present paper focused on the development of new antenna technologies for millimeter waves 5G communications. In this direction, a new two-ports Multiple Input Multiple Output (MIMO) antenna functioning in the mm-wave band is proposed in this paper to support 5G communications at 38 GHz. The proposed MIMO configuration has a size of 43  25 mm2 is printed on FR4 substrate material with a 0.8 mm thickness, a dielectric loss tangent of 0.02 and a relative permittivity of 4.4. By incorporating combinations of rectangular and triangular shaped slots into the patch elements and a partial ground plane with a rectangular slot, the desired band operation is achieved with enhanced gain and bandwidth. The considered antenna in this paper has a bandwidth of 3.38 GHz (36.8 GHz-40.18 GHz) in the desired band of 5G applications with isolation less than – 24 dB and peak gains of 4.85 dBi at 38.5 GHz. The proposed MIMO antenna covers many countries band like UK (37-40), USA (37-37.6), Canada (37.6-40.0) and Australia (39 GHz).
