“…To overcome this problem, numerous techniques have been proposed in the literature based on periodic inclusions such as metamaterials (MTM), soft electromagnetic surfaces (SES), and defected ground structures (DGS) . However, these approaches suffer from extremely narrow bandwidths because they employ artificial structures, which are highly resonant in nature.…”

“…To reduce mutual coupling in MIMO antennas, the literature reveals that the decoupling elements are either inserted in the space between the radiating elements to reduce surface waves in narrow‐banded microstrip antennas with full ground plane or on the partial ground in the form of slits or neutralization lines connecting the Planar Monopole Antennas (PMAs) . A neutralization line positioned above a partial ground plane is proposed by Zhang and Pedersen to increase the isolation between two circular monopole antennas separated by 2.2 mm above 22 dB over the frequency range of 3.1‐5 GHz.…”

A new approach is presented in this paper to reduce mutual coupling between two closely‐spaced planar monopole antennas. The approach employs either two parallel metallic strips or a single strip with a meander‐shaped slotted pattern symmetrically placed between the two antennas with their edges being separated by 4 mm and 8 mm, respectively. The novel aspect of our approach is that the decoupling structures are not only confined in the space shared by the two planar monopole edges but are rather extended above the partial ground plane on one end and to the edge of the substrate on the other end. The design provided measured −10 dB impedance and − 20 dB decoupling bandwidths extending from 1.65 GHz to 4 GHz, and 1.43 GHz to 3.7 GHz, respectively, and the measured realized gains at 2.45 GHz are 3.81 dBi and 2.14 dBi, respectively. The proposed arrays offer excellent MIMO performance in terms of envelope correlation coefficient and link efficiency in realistic MIMO propagation environments through the decoupled frequency regimes.
