Since the advent of mobile communication, the number of subscribers–and hence mobile devices–going online has witnessed an
exponential increase, and the industry has responded by being innovative in the different aspects of wireless communication, as for
instance transitioning from 4G to 5G networks. One of the key enabling technologies for bandwidth and speed enhancement
technologies of 5G networks is the use of millimeter waves. While several bands above 6 GHz have received approval for 5G, todate most of the research and development efforts have focused on the 28 GHz and 38 GHz [1-2].
In order to meet the needs of modern 5G wireless communication system, study of the 5G smartphone antenna has great application
value. 5G has become a hot spot in the field of mobile communications both at home and abroad.
