Abstract

In this paper, a 2×2 multiple-input-multiple-output (MIMO) assembly of an elliptical-shaped millimeter-wave (mm-wave) antenna with defected-ground structures (DGS) is presented. The antenna is integrated with ring slot-shaped cut-outs as DGS on the bottom ground to generate multiple resonances combined in a wide bandwidth of 25.0-29.7 GHz. The simulated results show an efficiency above 75% and realized gain above 4.5 dBi in the entire range with a peak gain of 7.64 dBi at 27 GHz. The proposed MIMO antenna is well-suited for the 6 th Generation (6G) wireless applications.
