“…The power transmission of a stacked dipole antenna can be enhanced by using an array of SRRs as a cover. 210 The SRR monolayer cover, having a negative permeability, enhances magnetic resonance strength and thereby increases the radiated power. A metamaterial-based thin planar lens antenna has been proposed for massive multiple-input/multipleoutput (MIMO) system.…”

The performance of microwave devices mainly depends on the properties of materials used in the fabrication. Knowledge of material properties at microwave frequencies is a prerequisite to select suitable materials for various microwave applications and vice versa. In this review, seven categories of materials and their applications in a microwave regime are elaborately discussed. The categories include magnetic materials, carbon-based materials, flexible or stretchable materials, biomaterials, phantoms, tunable materials and metamaterials. A brief overview of other important microwave materials such as low-loss ceramic dielectric materials, low-loss polymer ceramic composites, glass ceramics and multilayer ceramics is also given. The objective of this review is to expose the world of materials for wide microwave applications and thereby properly assisting the material selection for specific applications. Moreover, this review has dual significance. It helps material scientists to develop new materials and modify the properties of the available materials with respect to the application requirements. It also assists microwave engineers to select and use appropriate materials for different microwave applications.

“…Compared to the conventional microstrip antennas, the antennas using metamaterial can realize higher performances, e.g. reducing the size, increasing the radiation gain, and enhancing the bandwidth [11][12][13][14][15][16]. Therefore, by introducing all-dielectric metamaterial into reflectarray antenna, the wider band, higher gain and lower cost reflectarray antennas can be realized [17][18][19][20][21][22].…”

A form of reflective half-wave plate based on all-dielectric 3D-printed metasurface is proposed in this paper. The element of the proposed reflective half-wave plate consists of a novel hexagonal prism dielectric resonator (HPDR), a square substrate and a ground plane. The designed HPDR element can effectively convert the incident linearly polarized (LP) waves into the reflected circularly polarized (CP) waves. Meanwhile, an approximately linear reflection phase ranging over 360 • of HPDR element is realized by varying the height of HPDR, which can significantly simplify the design procedure. In addition, based on the proposed HPDR element, a CP dielectric reflectarray antenna is designed. In order to verify the feasibility of the proposed design method, the dielectric reflectarray antenna with LP feeding is fabricated and measured, which can achieve a 1 dB gain bandwidth of 17.9% and a 3 dB axial-ratio bandwidth of 15%. A good agreement between the simulation and measurement is also observed. To the best of authors' knowledge, the broadband CP dielectric reflectarray antenna based on all-dielectric 3D-printed metasurface may be the first ever reported.
