“…The symmetrical E-shaped patch antenna [5] can also achieve wide impedance bandwidth, but it has only one polarisation and its length is greater than 0.5𝜆 0 . The antennas in [12,15,16] can realize dual polarisations, but the relative operating bandwidth of these antennas are less than 30% which cannot cover the candidate frequency bands from 24 GHz to 40 GHz. The length and width of the antenna in [15] are both greater than 0.5𝜆 0 .…”

“…However, the above-mentioned antennas have only one linear polarisation. Recently, several kinds of dual-polarised antennas have been developed, such as aperture-coupled antennas [11,12], cavity-backed slot antennas [13], ME dipoles [14], and stacked patch antennas [15]. Nevertheless, the bandwidths of these dual-polarised antennas are all less than 30.0%.…”

A dual-polarized symmetrically cross-slotted square patch (SCSSP) antenna with multimode resonance is proposed for 5G millimeter-wave broadband applications. A symmetrical cross-slot is etched on the square patch surface to change the original E-field distribution where a whole square patch is cut into four disconnected equal parts. For both polarizations, this etching also tunes the resonance frequencies of the two modes to be sufficiently close to each other. Therefore, the antenna can realize good impedance performance within the wide designated bandwidth. Dual-polarized radiation of the SCSSP is vertically excited by three bow-tie-shaped slots and fed by two orthogonal substrate integrated coaxial lines. Simulated and measured results show that the fabricated prototype achieves a broad overlapped impedance bandwidth of 50.0% (24-40 GHz), isolation higher than 30 dB between the two input ports, stable radiation pattern, and low cross-polarization over the operating band. Moreover, the proposed SCSSP antenna with compact size, planar shape, and simple vertical feeding is very well-suited for two-dimensional array design.

“…A higher gain antenna is needed, and thus array structures were suggested in many research to have a higher gain performance system with the ability to switch the beam and avoid interferences. Antenna array and multi-beam antennas are widely used in the wireless communications field where 5G base stations are integrated with multiple antennas that would be compatible for high capacity, high gain, and high efficiency [1]- [3]. Specifically, antenna array and multi-beam antennas increase the capacity The associate editor coordinating the review of this manuscript and approving it for publication was Yang Yang . and cover a broader range of locations, which leads to improving the whole base station systems [4].…”

A Beam-Split Metasurface Antenna for 5G Applications

et al. 2022

This article presents a hybrid metasurface split beam antenna for fifth-generation (5G) mobile applications at 3.5 GHz. Multi-beam antennas with high directivity are required for a 5G mobile network. It can be achieved by having an array antenna. Using an antenna array at low frequency increases the complexity and size of the whole network. Therefore, a metasurface (MS) is proposed to direct surface current and to have high gain and multibeam properties. To achieve that, a square split ring resonator (SSRR) and U-shaped unit cell metasurface is implemented as a superstrate to a single square patch antenna. The manipulation of this hybrid metasurface configuration can create opposite current flow on the unit cell and thus split the beam. The hybrid metasurface superstrate and antenna are fabricated on FR-4 (εr = 4.4, tanδ = 0.02). Results show that the antenna resonates well at 3.5 GHz, with a less than −10 dB reflection coefficient. The arrangement of the unit cells on the superstrate metasurface is able to split the current, and thus the radiation pattern beam is split into two beams in the E-plane at ± 45 • . This antenna is a good candidate for future 5G Pico cell base stations in urban or suburban areas with high capacity and interferences.

A 2-D multibeam antenna based on the dimension gradient metasurface is proposed in this paper. The metasurface is composed of four subunits formed by square patches with the dimension gradient in a 5 Â 5 pattern. When the dimension gradient of subunits is adjusted, the beam direction in the azimuth plane can be switched in a larger range. Furthermore, by introducing L-shaped slots in the ground plane and two stubs on the feeding lines, the peak gain, sidelobe level and isolation of the antenna can be improved. Meanwhile, the antenna maintains a low profile of 0.06 λ 0 . The measured results show that the impedance bandwidth of the antenna is 16.5% (5.5-6.49 GHz). Four beams are generated and pointed at (φ 0 , θ 0 ) = (70 , 23 ), (160 , 24 ), (250 , 21 ), and (340 , 24 ). The peak gains of the beams reach 8.54 dBi.
