    Abstract: The present invention relates to a wave-absorbing metamaterial, comprising a substrate which is provided with two opposite lateral surfaces, wherein a plurality of periodically arranged artificial metal microstructures are attached on at least one of the two opposite lateral surfaces; when an electromagnetic wave having an incident direction vertical to the two opposite lateral surfaces of the substrate is transmitted to the wave-absorbing metamaterial, a relative permittivity of the metamaterial is substantially equal to a relative magnetic conductivity of the metamaterial. A wave-absorbing principle different from that of a conventional wave-absorbing material is employed on the wave-absorbing metamaterial; an ideal wave-absorbing effect is achieved by periodically arranging various artificial metal microstructures on the substrate and adjusting the artificial metal microstructures; and the wave-absorbing metamaterial has the advantages of minor weight, small thickness and simply adjustable electromagnetic parameters.

    Abstract: A front feed microwave antenna, which comprises a radiation source, a first metamaterial panel used for radiating an electromagnetic wave emitted by the radiation source, a second metamaterial panel, and a reflective panel affixed to the back of the first metamaterial panel. The electromagnetic wave is emitted via the first metamaterial panel, refracted by entering the second metamaterial panel, reflected by the reflective panel, and finally re-refracted by reentering the second metamaterial panel, then finally parallel-emitted. Employment of the principle of metamaterial for manufacturing the antenna allows the antenna to break away from restrictions of conventional concave lens shape, convex lens shape, and parabolic shape, thereby allowing the shape of the antenna to be panel-shaped or any shape as desired, while allowing for reduced thickness, reduced size, facilitated processing and manufacturing, reduced costs, and improved gain effect.

    Abstract: The present invention relates to a metamaterial and a metamaterial antenna. The metamaterial is disposed in a propagation direction of the electromagnetic waves emitted from a radiation source. A line connecting the radiation source to a point on a first surface of the metamaterial and a line perpendicular to the metamaterial form an angle θ therebetween, which uniquely corresponds to a curved surface in the metamaterial. Each point on the curved surface to which the angle θ uniquely corresponds has a same refractive index. Refractive indices of the metamaterial decrease gradually as the angle θ increases. The electromagnetic waves propagating through the metamaterial exits in parallel from a second surface of the metamaterial. The refraction, diffraction and reflection at the abrupt transition points can be significantly reduced in the present disclosure and the problems caused by interferences are eased, which further improves performances of the metamaterial and the metamaterial antenna.

    Abstract: An antenna comprises a medium substrate and grounding units attached on the medium substrate. The antenna further comprises a metal structure attached on the medium substrate. The metal structure comprises an electromagnetic response unit, a metal open ring enclosing the electromagnetic response unit and a feeding point connected to an end of the metal open ring. The electromagnetic response unit comprises an electric-field coupling structure. This design increases the physical length of the antenna equivalently, so an RF antenna operating at an extremely low frequency can be designed within a very small space. This can eliminate the physical limitation imposed by the spatial area when the conventional antenna operates at a low frequency, and satisfy the requirements of miniaturization, a low operating frequency and broadband multi-mode services for the mobile phone antenna. Meanwhile, a solution of a lower cost is provided for design of the antenna of wireless communication apparatuses.
