A multiple-input-multiple-output (MIMO) antenna array for broadband 5G new radio (5G NR) metal-frame smartphone applications is proposed. The MIMO antenna array is realized by loading eight identical antennas (Ant1-Ant8) into the metal frame of the smartphone to form an eight-antenna array for the s...
