“…The series of uniform or non-uniform array structures further improves the gain and bandwidth of the dipole antenna [ 10 , 11 , 12 ]. A balun can also be used for better impedance matching at the desired resonance [ 13 ]. The magneto-electric dipole antennas in [ 10 , 11 , 12 , 13 ] achieve wide bandwidth with good gain.…”

This article presents a planar, non-angular, series-fed, dual-element dipole array MIMO antenna operating at 28 GHz with the metasurface-based isolation improvement technique. The initial design is a single-element antenna with a dual dipole array which is series-fed. These dipole elements are non-uniform in shape and distance. This dipole antenna results in end-fire radiation. The dipole antenna excites the J1 mode for its operation. Further, with the view to improve channel capacity, the dipole array expands the antenna to a three-element MIMO antenna. In the MIMO antenna structure, the sum of the J1, J2, and J3 modes is excited, causing resonance at 28 GHz. This article also proposes a metasurface structure with wide stopband characteristics at 28 GHz for isolation improvement. The metasurface is composed of rectangle-shaped structures. The defected ground and metasurface structure combination suppresses the surface wave coupling among the MIMO elements. The proposed antenna results in a bandwidth ranging from 26.7 to 29.6 GHz with isolation improvement greater than 21 dB and a gain of 6.3 dBi. The antenna is validated with the diversity parameters of envelope correlation coefficient, diversity gain, and channel capacity loss.

“…A balun can also be used for better impedance matching at the desired resonance [ 13 ]. The magneto-electric dipole antennas in [ 10 , 11 , 12 , 13 ] achieve wide bandwidth with good gain. However, these structures are complex and multi-layered, which makes it challenging to fabricate and align them precisely.…”
