Abstract
The fifth-generation (5G) era has already arrived and many applications are prospering. The multiple input multiple output (MIMO) system is the key to enhancing channel capacity for both the fourthgeneration (4G) wireless communication and 5G systems. For a smartphone, the most challenging task for antenna engineers is to accommodate the numerous 4G and 5G multi-port antennas while avoiding mutual coupling problems (Li Y et al., 2009, 2012; Hong, 2017; Sharawi et al., 2017). Therefore, implementing multiple antennas within a small space is a worthwhile topic to study, especially for antennas operating at the same frequency.
