Development of quad MIMO antenna with evaluation of TARC performance
A 4× 4 multiple input multiple output (MIMO) antenna is designed to achieve enhanced gain and isolation for the proposed 6 G frequency band (7–24 GHz), covering C, X, Ku, K, and Ka bands. The initial design features a printed ring-shaped monopole antenna integrated with a four-spoke arm, rotated at 45°. A defected grou...
