A Compact E-Shape Patch Antenna for 5G Millimeter Wave Applications

A small scaled rectangular patch antenna has been transformed into a novel E-shaped design, proving invaluable in wide-ranging 5G mm wave applications such as satellite communications, radar navigation, massive IoT, and WLAN networks. In this research, the suggested antenna provides a delightful triple band frequency coverage at 42.66 GHz, 61.32 GHz, and 76.32 GHz, each with a spectrum width of 2.04 GHz, 2.16 GHz, and a remarkable 14.28 GHz, respectively. Using CST simulation software, a compact 4 x 5 x 0.55 mm
