“…Other works that used slots and parasitic elements to mitigate the mutual coupling between antenna array elements have been recently reported in [25,26]. In [25], a compact high isolation three-sector linear array for point-to-point or point-to-multipoint data communications is proposed, whose high isolation is achieved using parasitic elements that can be used for dual-polarization decoupling. A novel slot-array DGS for decoupling microstrip antenna array is proposed in [26], where the highest isolation is achieved by applying the slot-array DGS when the edge-to-edge spacing between circularly polarized (CP) antenna elements is 0.057 wavelength.…”

This paper presents a compact dual-polarized multiple-input multiple-output (MIMO) antenna for fifth generation (5G) and wireless local area network (WLAN) applications. At first, a compact two-element dual-polarized MIMO antenna designed to operate at 3.5 GHz was developed. After that, some modifications were performed in the initial configuration, and a compact two-element dual-polarized MIMO was designed to operate at 3.5 and 5.35 GHz. A simple decoupling technique using parasitic element and slot was used to enhance the isolation between the radiating elements and to achieve an isolation above 18 dB over the band ranging from 3.4 to 3.6 GHz for the first antenna, and to achieve isolations above 19.8 dB over the first band ranging from 3.4 to 3.6 GHz and above 16.75 dB over the second band ranging from 5.15 to 5.85 GHz for the second antenna. Simulations were performed in the Ansoft HFSS software for numerical characterization and the prototype was fabricated with FR-4 dielectric and measured, presenting a good agreement between simulated and measured results. Furthermore, the envelope correlation coefficient (ECC) and the diversity gain (DG) were analyzed and present good results.

“…8,9 Although the Yagi array yields higher gain, its interelement spacing of 1.83λ results in larger dimensions, leading to increased wind load. 10 On the other hand, wideband high-efficiency electromagnetic structure (WHEMS) antennas possess smaller end-fire size and wider bandwidth, [11][12][13][14][15][16][17] with relatively smaller interelement spacing, yet they do not exhibit substantial gain improvement. 18 Addressing the coupling issue is pivotal for enhancing the gain of linear antenna array.…”

A compact series‐fed high‐quality linear array antenna for 5G maritime communication is proposed. Building upon the wideband high‐efficiency electromagnetic radiation structure (WHEMS), a linear integrated series‐fed method is proposed, enhancing applicability in maritime environments. A self‐decoupling structure without the parasitic elements is introduced, resulting in a 7 dB increase in isolation while achieving array spacing of less than half the wavelength. The antenna has an impedance bandwidth of 19.9% (676–825 MHz) to cover the maritime 700 MHz application band, a high gain of 13–14.2 dBi, and a smaller volume compared to classical Yagi arrays with the same gain level. Furthermore, it exhibits characteristics such as low wind load, cost‐effectiveness, and high voltage resistance. The proposed antenna will play a vital role in the construction of the current 5G maritime communication network.
