Millimeter wave phased array antennas have been developed for a variety of applications, such as communication, radar, and imaging systems. Recently, extensive research has been conducted on the use of millimeter wave phased array antennas for 5G communication systems, which are expected to provide faster data rates and lower latency than previous wireless technologies. However, the performance of phased array antennas can be affected by the scanning angle, as the mutual coupling between antenna units changes
