“…In previous studies, researchers have explored multiband MIMO antennas with dual ports [19][20][21][22][23] and quad/multiport ports [24][25][26][27][28][29]. The dual-port antenna design proposed in [19] utilized a defective ground and parasitic element to create a dual-band antenna suitable for WLAN applications.…”

This paper presents a novel design for and an experimental study of a dual-polarized quad-port MIMO antenna. The design achieves resonance at five distinct frequency bands with reduced mutual coupling. The design includes a single annular ring slot, four truncated rectangular corners, and a truncated aperture to improve resonance behavior. The design is then extended to a four-port MIMO antenna by including a ground-plane slit to enhance isolation between antenna elements at the center resonance band. The antenna achieves resonances at 5 distinct bands, ranging from 1.5 to 8.4 GHz, with significant mutual coupling reductions. The resonances of the quad-port pentaband MIMO antenna are achieved at 1.55 GHz (1.5–1.65 GHz), 2.5 GHz (2.4–2.7 GHz), 5.2 GHz (5–5.85), 7.3 GHz (7.1–7.4), and 8.15 GHz (7.9–8.4), with respective mutual coupling reductions of 27 dB, 37 dB, 21 dB, 29 dB, and 21 dB. Additionally, the 3 dB axial ratio bandwidth (ARBW) is observed at 6.5% (1.5–1.6 GHz) and 15% (2.4–2.7 GHz) in 2 distinct bands, and the envelope correlation coefficient and diversity gain are calculated within the specified band range. Experimental measurements of the prototype for the quad-port antenna are conducted, with excellent agreement found between the results and the simulations.

“…However, the performance of the MIMO system is degraded by the mutual coupling between antenna elements. To achieve the high isolation between antenna elements, different types of isolation techniques are reported in the literature for-instance transmission lines (S 21 > −15 dB) [15], diagonally opposite position (S 21 > −12 dB) [16], orthogonality between elements (S 21 > −12 dB) [17], (S 21 < −14 dB) [18], (S 21 = −18 dB) [19], placing in opposite manner (S 21 > −19 dB) [20], transmission lines and slots (S 21 > −25 dB) [21], a shorting strip and stub (S 21 > −27 dB) [22], a stepped slot ended with an ellipse (S 21 < −18 dB) [23], a parasitic element (S 21 < −15 dB) [24], a decoupling structure (S 21 < −24 dB) [25], separation between elements (S 21 < −20 dB) [26], vertical position (S 21 = −16.5 dB) [27], meandering line and decoupling structure (S 21 < −25 dB) [28], (S 21 < −26.57 dB) [29], symmetric slot lines and reversed alignment of radiators (S 21 > −15 dB) [30], defected ground plane and neutralization lines (S 21 < −17 dB) [31], microstrip resonator (S 21 > −35 dB) [32], a T-shape isolator (S 21 > −12.4 dB) [33], a decoupling structure with branches and slots (S 21 < −15 dB) [34], and parallel arrangement (S 21 > −18 dB) [35].…”

In this work, a novel 4 element Multi-Input Multi-Output (MIMO) antenna is reported. The proposed antenna has a size of 50 × 50 × 1.6 mm 3 is printed on the FR-4 substrate having dielectric constant ε r = 4.4 and loss tangent (tan δ = 0.02). The four antenna elements are positioned in each corner of the PCB board in an orthogonal manner such that they can provide better isolation between antenna elements. The proposed MIMO antenna is designed to operate in frequency bands of 2.25 GHz to 2.4 GHz and 4.7 GHz to 6.3 GHz. The lower band ranges from 2.25 GHz to 2.4 GHz and covers 2.3 GHz WiBro applications while the upper band ranging from 4.7 GHz to 6.3 GHz is useful for HiperLAN and Wi-MAX applications. The proposed antenna acquires return loss less than −10 dB and isolated by more than 16 dB throughout the dual operating bands. The structure exhibits stable gain and radiation patterns. Various diversity performance metrics including envelope correlation coefficient (ECC), diversity gain (DG), and mean effective gain (MEG) are evaluated and are within acceptable limits. Full wave simulation results in terms of impedance and radiation characteristics are presented to evaluate the proposed antenna performance in an installed environment.

In this paper, a novel compact single element G-shaped Asymmetric Coplanar Strip (ACS) fed antenna and its four-element printed multiple-input multiple-output (MIMO) antenna have been presented with multi-band frequency characteristics. The proposed MIMO antenna has been fabricated on an FR-4 substrate (46 × 46 × 1.6) mm 3 with dielectric constant ε r = 4.4. The desired isolation between the elements (−18 dB) is achieved by placing the antenna elements orthogonal to each other. Simulated and measured results show that return loss (S 11 ) for the proposed MIMO antenna is less than −10 dB in the operating bands, with frequency ranging 2.30-2.45 GHz, 3.36-3.65 GHz, and 4.53-5.88 GHz, respectively, which ensures its operation in multiple frequency bands. Moreover, these bands are obtained for 2.3 GHz WiBro,LTE and 5G NR to cover B40/B42/N30/N40/N97 together with 3.5 GHz/5 GHz WiMAX/WLAN band applications. Meanwhile, the diversity performance characteristics like ECC (Envelope Correlation Coefficient), MEG (Mean Effective Gain), DG (Diversity Gain), Total Active Reflection Coefficient (TARC), and Channel Capacity Loss (CCL) have been calculated and are presented in this paper. The correlation coefficient is found to be less than 0.001 with a diversity gain greater than 9.95, and an acceptable channel capacity loss is less than 0.4 bits/s/Hz.
