“…The antenna has electrical dimensions measuring 0.56λ 0 × 0.56λ 0 , ECC of 0.01, and demonstrates isolation surpassing 13 dB. Another approach outlined in [16] employs a quad-element wideband printed modified monopole-based MIMO antenna system for the same frequency range, utilizing a ground structure with vertical slots and a single circular slot to enhance isolation.…”

A wideband, dual-element MIMO antenna operating in 2.83-7.21 GHz frequency bands is presented in this study. The proposed design consists of a stub-loaded partial ground plane and a stepped feedline with a dual circle-shaped radiator on top. The designed MIMO antenna operates from 2.83 to 7.21 GHz, covering the C band (4-8 GHz) and 5G (sub-6 GHz) applications. The peak gain observed is 4.8 dBi at 6.2 GHz, with a maximum efficiency of 92% at 3.2 GHz. The minimum port isolation and ECC over the bands 2.83-7.21 are observed as 22 dB and 0.003, respectively. To achieve the best outcome, a parametric analysis of the proposed antenna is also simulated. Various diversity characteristic metrics, including diversity gain (DG), mean effective gain (MEG), total active reflection coefficient (TARC), channel capacity loss (CCL), and ergodic channel capacity (CC), are thoroughly analyzed to determine how well the MIMO antenna performs in terms of diversity. In all operating bands, the measured values provide good agreement with simulation results, indicating a strong candidacy for operation in the investigated bands.

“…In [10], the authors analyze the influence of the three structures of split-ring resonator, non-bianisotropic split-ring resonator, and spiral resonator on the decoupling. In addition, a capacitive coupling between the π -line and the two curved stubs is adopted to form the decoupling network [11]. Furthermore, a novel diamond-shaped patterned ground resonator is used to achieve the decoupling [12].…”

A printed multiband Multi-Input Multiple-Output (MIMO) antenna is proposed in this paper. This MIMO antenna system comprises two symmetric printed monopole antennas. Each antenna element consists of multiple bend lines, producing four resonant modes and covering the GSM900, PCS, LTE2300, and 5G bands. Simulated and measured results prove that the proposed MIMO antenna can be applied to traditional 2G, 3G, 4G, and present 5G mobile communication. By etching four inverted L-shaped grooves on its ground plate, mutual coupling between the adjacent antenna elements has been suppressed. This makes the |S21| at all four resonant modes is lower than −40 dB. In addition, its low coupling mechanism has been analyzed by surface current distribution. The designed multiband MIMO antenna provides an idea of reference to realize low mutual coupling between antenna elements, which is also realizable in infrared or optical regimes with appropriate designs.
