This paper presents the design of 8 x 8 MIMO antennas for future 5G devices such as smart watches and dongles etc. Each antenna of the MIMO configuration occupies 3 x 4 mm2 and is printed on the top layer of the substrate in the form of a rotated H-shaped patch. The substrate used for the design is a 31.2 x 31.2 x 1.57 mm3, Rogers RT-5880 board, with dielectric constant of 2.2. The top layer of the substrate has eight MIMO antennas whereas, the bottom layer is composed of ground plane. The ground plane is an Electromagnetic Band Gap (EBG) based structure designed for the enhancement of gain and efficiency. Each antenna is fed from the bottom layer of the substrate through vias to avoid any spurious radiation. The MIMO antennas resonate at 25.2 GHz with a 6 dB percentage bandwidth of 15.6%. The gain attained by the antennas in the entire bandwidth is above 7.2 dB with maximum value of 8.732 dB at the resonant frequency. Likewise, the value of efficiency attained by the antennas in the entire bandwidth is above 65% with maximum of 92.7% at the resonant frequency. The simulation and measurement results have substantiated a good performance of the MIMO antennas, thus making them suitable for compact 5G devices.
