5G evolution promoting innovation of antenna systems
Abstract: We introduce the basic concept, background, and development of mobile communication systems from the first generation (1G) to the fifth generation (5G) including their antenna systems. We also describe the requirements for 5G networking and optimization of antenna systems, and present the basic principle of three-dimensional array antennas. Weight optimization methods of massive multiple-input multiple-output (MIMO) antennas are proposed and verified. Finally, several ideas are given to solve the problem of power consumption of 5G antenna systems.
Key words: Fifth generation (5G), Massive multiple-input multiple-output (MIMO) antenna array, Power consumption, Weight optimization
