“…The antenna presented in [ 15 ] with a smaller size achieves two beams of radiation, but it cannot switch beams. Antennas using multiple ports to achieve multiple beams were proposed [ 21 , 22 , 23 , 24 ], but they can only achieve one beam at the same time, and the real-time switching of different ports is relatively complex. The antenna proposed in [ 25 ] achieved flexible beam control by placing programmable metasurface elements in SIW antennas, but the size of the antenna is relatively large.…”

In this paper, we proposed a multibeam switching antenna based on a low-cost reconfigurable hybrid metasurface applied for beamforming systems. The antenna consists of two parts: a microstrip feed antenna and a transmission hybrid metasurface. The latter is composed of three types of units with different amplitude and phase responses to electromagnetic waves so as to control the beams of the feed antenna. Sixteen PIN diodes are arranged in the metasurface with a simple bias network. When two different direct-current voltages are applied to the PIN diodes, the antenna can dynamically switch between two beams and four beams. For demonstration, the proposed antenna is fabricated, and the measured results show that the antenna operates at 9.07–9.42 GHz (−10 dB bandwidth) with a total size of 1.80λ0 × 1.52λ0 × 0.22λ0 (λ0 corresponds to the wavelength of 9.28 GHz in free space). With the merits of a compact structure, low cost and good radiation performance, the proposed design is suitable for beamforming applications.

“…In various MIMO antenna designs, the metamaterial is laid above [ 17 , 33 , 34 , 35 , 36 ] or beneath [ 13 , 37 ] the antenna radiator with an air gap. In these instances, the MM performs as a superstrate or reflector that manipulates the gain, isolation, and bandwidth of the antenna.…”

This article demonstrates a compact wideband four-port multiple-input-multiple-output (MIMO) antenna system integrated with a wideband metamaterial (MM) to reach high gain for sub-6 GHz new radio (NR) 5G communication. The four antennas of the proposed MIMO system are orthogonally positioned to the adjacent antennas with a short interelement edge-to-edge distance (0.19λmin at 3.25 GHz), confirming compact size and wideband characteristics 55.2% (3.25–5.6 GHz). Each MIMO system component consists of a fractal slotted unique patch with a transmission feed line and a metal post-encased defected ground structure (DGS). The designed MIMO system is realized on a low-cost FR-4 printed material with a miniature size of 0.65λmin × 0.65λmin × 0.02λmin. A 6 × 6 array of double U-shaped resonator-based unique mu-near-zero (MNZ) wideband metamaterial reflector (MMR) is employed below the MIMO antenna with a 0.14λmin air gap, improving the gain by 2.8 dBi and manipulating the MIMO beam direction by 60°. The designed petite MIMO system with a MM reflector proposes a high peak gain of 7.1 dBi in comparison to recent relevant antennas with high isolation of 35 dB in the n77/n78/n79 bands. In addition, the proposed wideband MMR improves the MIMO diversity and radiation characteristics with an average total efficiency of 68% over the desired bands. The stated MIMO antenna system has an outstanding envelope correlation coefficient (ECC) of <0.045, a greater diversity gain (DG) of near 10 dB (>9.96 dB), a low channel capacity loss (CCL) of <0.35 b/s/Hz and excellent multiplexing efficiency (ME) of higher than −1.4 dB. The proposed MIMO concept is confirmed by fabricating and testing the developed MIMO structure. In contrast to the recent relevant works, the proposed antenna is compact in size, while maintaining high gain and wideband characteristics, with strong MIMO performance. Thus, the proposed concept could be a potential approach to the 5G MIMO antenna system.

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.
