“…This kind of reflectarrays provide very wideband response in frequency. Another version of a dielectric reflectarray is published in [157], where the protrusion (C-shaped in this case) is not supported on a dielectric panel but on the ground plane directly. The properties are actually similar to the dielectric reflectarrays previously cited.…”

Metamaterials are artificially engineered devices that go beyond the properties of conventional materials in nature. Metamaterials allow the creation of negative refractive indexes, light trapping with epsilon-nearzero compounds, bandgap selection, superconductivity phenomena, non-Hermitian responses and, more generally, to manipulate the propagation of electromagnetic and acoustic waves. In the past, low computational resources and the lack of proper manufacturing techniques have limited the attention to 1-D and 2-D metamaterials. However, the true potential of metamaterials will be ultimately reached in 3-D configurations, when the degrees of freedom associated to the propagating direction are finally exploited in design. This is expected to lead to a new era in metamaterial field, from which future high-speed and low-latency communication networks can benefit. Here, a comprehensive overview of the past, present and future trends related to 3-D metamaterial devices is presented, focusing on efficient computational methods, innovative designs and functional manufacturing techniques.

“…Existing research have shown that dielectric reflectarray have low loss and well performance in microwave frequencies, which can achieve ultra-wideband. [20][21][22][23][24] The dielectric reflectarray of literature 20 adopts the fused deposition modeling (FDM) printed to achieve reconfigurable polarization mechanically. The dielectric resonator reflectarray 21 achieved a gain of 28 dBi at 30 GHz in FDM printed.…”

An ultra‐wideband 3D‐printed dielectric reflectarray antenna (DRA) is proposed in this letter. The dielectric reflectarray unit (DRU) adopts the photosensitive resin therm1220, which dielectric constant of 3.97 is conducive to improving the bandwidth. Through adjusting the size of the DRU, the reflection phase can be adjusted. The dielectric reflectarray is 23 × 23 element which printed by stereo lithography apparatus (SLA) and is realized by installing a metal plate with four resin screws. The measured of the gain covers 25.8–28.9 dBi from 27.5 to 38 GHz. And the 3‐dB gain bandwidth of measured is 32.1%. The measured aperture efficiency is basically above 30% from 28 to 35 GHz. The maximum gain is 28.1 dBi at 30 GHz, and the aperture efficiency is 39% during measurement. The 3 dB beam width of the E‐plane and H‐plane are both about 5.4° in Ka‐band. A good agreement can be observed between measurement and simulation.

“…With the fast prototyping capability of irregular shapes, three-dimensional (3D) printing has been used for fabricating DR reflectarrays in recent years [15]- [18]. [15] and [17] both proposed 3D printed dielectric reflectarrays with variable height elements at sub-millimeter-waves.…”

“…By using the acrylonitrile butadiene styrene (ABS) material, a 3D-printed dielectric reflectarray with variable width unit cells was designed in [16]. In [18], a polarization-reconfigurable reflectarray was realized by 3D printing for 5G millimeterwave applications. All these designs are also limited to low relative permittivity materials (ɛr < 4.4) and therefore resulting in a large size or non-planar configuration.…”

For the first time, a millimeter-wave dual-polarized dielectric resonator (DR) reflectarray fabricated by three-dimensional (3D) printing with high relative permittivity materials is presented. The unit cell of the reflectarray is composed of two elliptical DRs orthogonally placed in the center. A base layer of dielectric slab at the bottom of the unit cell is for fixture and connection with its adjacent elements. For each polarization, only the length of the long axis of one elliptical DR is varied independently to obtain the required reflecting phase response. Due to the orthogonality, high isolation and design independence between the two polarizations can be also obtained. A dual-polarized square DR reflectarray with 16 × 16 elements working in the Ka-band was designed, printed, and measured for demonstration. A measured peak antenna gain of 22.53 dBi was obtained, achieving a gain enhancement of 7.43 dB as compared with that of the feed horn.INDEX TERMS Dual polarization, three-dimensional printing, dielectric antenna, reflectarray, high-gain antenna.
