Gain and isolation enhancement of a wideband MIMO antenna using metasurface for 5G sub-6 GHz communication systems

"Abstract This work includes the development of a compact metasurface -integrated wideband multiple-output antenna for fifth generation sub-6 GHz wireless communications networks. U00d7 0. 05 bb u01d7 0. 02 mmu03bb u00d7 0. 02 u03bb>u00d7 0. 02 bb and its results are evaluated on a proposed 10 u00d7 10 array of a square enclosed circular ring resonators embedded in the same substrate material, as shown by a suggested Rogers RT5880 substrate with a minimum dimension of 1. 05 bb u03bbbb u00d7 0. 05 u03bbb u03bbbbb u03b u03bbb u03bbbbbbbbbbbbbbbbbbbbbbbbb u03bbb resonators within u03bbbbbbbbbbb u03bbbbbb u03bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb In the 5G sub-6 GHz spectrum, the proposed 4-port MIMO antenna delivers a high realized gain of 8. 3 dBi relative to previous MIMO antennas with a high average total yield of 82% and is in good accordance with measured measurements. "In addition, the assembled MIMO antenna has outstanding diversity characteristics in respect of envelope correlation coefficient lower than 0. 004, providing increased diversity among MIMO components and high isolation between MIMO components.

A novel design of wide and multi-bands 2×2 multiple-input multiple-output antenna for 5G mm-wave applications

"The antenna is made in a rectangular zigzag pattern with slots to make the antenna operate at various frequencies. " The antenna dimensions for four elements are 29u00d749 mm 2, according to the most significant feature of the design, its small size and compact structure compared to designs reported by researchers in previous literature. The antenna results based on CST Studio Suite's results are excellent, with reflectivity coefficients of the antenna reflecting the antenna's reflection coefficients at six main frequencies of 39. 128 GHz, 42. 992 GHz, 55. 472 GHz, 55. 672 GHz, and 59. 288 GHz at 62. 188 GHz, 55. 472 GHz, 51. 972 GHz, 55. 672 GHz, 55. 672 GHz, 51. 972 GHz,.

Dual-Band Circularly Polarized Hybrid Dielectric Resonator Antenna for 5G Millimeter-Wave Applications

"This paper describes a dual-band circularly polarized rectangular dielectric resonator antenna for 5G millimeter wave wireless communications. " To boost the DRA's bandwidth, the MCF slot can also function as a radiator at 26 GHz and 39 GHz. paraphrasedBic and 6. 78 dBic for the lower and upper bands, respectively, with peak bandwidths of 19. 8% and 7. 8%. The measured results show that the new dual-band CP DRA achieves 3 dB axial-ratio DRA achieves 3 dB axial-ratio bandwidths of 19. 8% and 7. 8%, with peak gains of 5. 72 dBic and 6. 74 dBic for the lower and upper bands.
