Abstract
This research study introduces a novel small antenna with wideband capacity for the higher frequency range. As a possible contender for 6 G wireless networks, the proposed antenna is designed to target the 6 G Millimeter-Wave (mmWave) operating bands spanning 25 GHz to 33.5 GHz. With a microstrip patch structure fed by a coplanar waveguide (CPW) with the defected ground structure (DGS), a single antenna is introduced and then a design of 2×2 MIMO antenna is presented. The single antenna has 2 elements while the 2×2 MIMO antenna has 8 elements. It achieves remarkably well in terms of return loss of 8.5 GHz wideband, which is anticipated to be used for several applications in 6 G mmWave technology.
