Dual-Band Four-element MIMO Side-Edge Antenna for Modern Wireless Communications

A dual-band with a four-element MIMO antenna for future 5G mobile applications is presented. The single-element antenna consists of several microstrip lines arranged in a way to cover 5G and Wi-Fi 6 bands. The results demonstrate that the intended design has a low mutual coupling of −18 dB and −28 dB for the two bands respectively and has an almost omnidirectional pattern with the maximum gain achieved is 6.63 dB. The proposed antenna has an efficiency (61% – 76%), envelope correlation coefficient is much less than (EEC < 0.015), diversity gain (DG > 9.95 dB), mean effective gain (MEG < 3dB), and finally, channel capacity loss (CCL < 0.10 bit/s/Hz). A simulation and analysis have been done using ANSYS HFSS software on a substrate of FR4 with an overall dimension of 150 x 75 x 0.8 mm
