“…The suggested MIMO antenna structure's ECC value in this research is below 0.0015 in the 22-30.4 GHz band and 0.0005 in the 36.1-44.6 GHz band, showing that the antenna elements have relatively little correlation with one another. It can be computed by implying equation (5) expressed in [36]: Diversity Gain (DG) quantifies the improvement in signal quality achieved by utilizing multiple antennas in a MIMO system compared to a single antenna system. It considers the decrease in fading and the increase in signal-to-noise ratio resulting from the usage of multiple antennas.…”

This article presents an unique configuration of Multiple-Input Multiple-Output (MIMO) antenna array for functioning at 27/38 GHz millimeter-wave 5G new radio (NR) frequency bands applications. The suggested antenna is constructed with four MIMO elements, containing total of eight identical patches arranged in a 2×4 array configuration. The array also includes a separate non-connected rectangular ground plane with an overall dimension of 32.4×32.8×0.8mm3. The single radiating patch elements are designed using spline resonator with H-shaped structures. The prototype model is realized using low cost FR-4 substrate and the obtained measurement results validate the analyzed simulated results. The suggested MIMO array antenna offers dual band operation with an impedance bandwidth of 8400 MHz covering 22 to 30.4 GHz and 8500 MHz ranging from 36.1 to 44.6 GHz. The proposed antenna achieves a peak gain of 8.75 dBi when operating at 27 GHz and 18.59 dBi at 38.1 GHz. Furthermore, it shows circular polarization characteristics by offering the axial ratio values significantly lower than 3 dB at 27 GHz and 38.1 GHz frequency bands. Additionally, the results indicate the favourable values of the diversity performance parameters with reference to Mean effective gain (MEG), Envelope correlation coefficient (ECC), Diversity gain (DG), Total active reflection coefficient (TARC), and Channel capacity loss (CCL). Moreover, it demonstrates high isolation (<-20 dB) within the desired bandwidth. These superior characteristics make it compatible for 5G NR frequency bands N257(26.5-29.5 GHz), N258 (24.5-27.5 GHz), N259 (39.5-43.5 GHz) and N260 (37-40 GHz), enabling its use in various countries including the China, European Union, Sweden, Korea, Japan, United States of America, Canada and Australia.

“…Decoupling is accomplished using different methods. Defected ground structures [ 10 ], decoupling networks [ 11 ], electromagnetic band gap structures (EBG) [ 12 ], neutralizing lines [ 13 ], parasitic or slot elements [ 14 ] and complementary split-ring resonator (CSRR) [ 15 ] are an example of such decoupling techniques. A UWB-MIMO antenna with dual ports is described in Ref.…”

“…2,3 To address these issues, multiple input multiple output (MIMO) antenna systems have been identified as a promising solution because they enable faster data speeds and increase channel capacity. While several MIMO antenna systems for 5G applications have been proposed in the literature, such as electromagnetic band-gap EBG based, 4,5 planar inverted F antenna pair-based, 6 a metamaterial, substrate integrated waveguide (SIW) and Dielectric Resonator Antenna based, 7 but these antennas suffer from complex geometry.…”

In this letter, a compact circular cavity‐backed, circularly polarized substrate integrated waveguide (SIW) multiband antenna is proposed. In the outer circular cavity, an array of two periodic metal slots, tilted at an angle, resonate at 25.32, 26.44, and 28.83 GHz, and the inner circular cavity's periodic slots radiate at 28.01 GHz. Two concentric SIW cavities are structured in such a distinct manner that no loss due to leakage takes place thus, achieving a maximum isolation of −43.8 dB at 28.83 GHz. The miniaturized antenna has dimensions of 2.2λo × 2.2λo × 0.1λo where λo is the operating wavelength. It achieves a maximum gain of 9.1 dBi at 26.44 GHz, and VSWR < 2 is achieved at all frequency bands. The antenna is circularly polarized at 26.44 and 28.01 GHz as well. The design results are plotted in the Ansys high‐frequency structure simulator version EM19.2 tool. The proposed antenna is fabricated and tested using an Anritsu Vector Network Analyzer version v4.0 with an anechoic chamber setup.
