Abstract: Complementary metamaterial elements provide an effective permittivity and/or permeability for surface structures and/or waveguide structures. The complementary metamaterial resonant elements may include Babinet complements of “split ring resonator” (SRR) and “electric LC” (ELC) metamaterial elements. In some approaches, the complementary metamaterial elements are embedded in the bounding surfaces of planar waveguides, e.g. to implement waveguide based gradient index lenses for beam steering/focusing devices, antenna array feed structures, etc.

Abstract: A front feed satellite television antenna includes a metamaterial panel. The metamaterial panel includes a core layer and a reflective panel. The core layer includes a core layer lamella which further includes a circular area and multiple annular areas distributed around the circular area. Within the circular area and the annular areas, refractive indexes are identical at a same radius, and within the respective areas, the refractive indexes decrease gradually as radius increases. The minimum refractive index of the circular area is less than the maximum the refractive index of the annular area adjacent thereto. For two adjacent annular areas, the minimum refractive index of the annular area at the inner side is less than the maximum refractive indexes of the annular area at the outer side. The metamaterial panel can replace conventional parabolic antenna, thus facilitating manufacturing and processing, and further reducing costs.

Abstract: The present disclosure discloses an antenna device, which comprises an array antenna and a power divider. The array antenna comprises a plurality of antenna units, and each of the antenna units comprises a conductive sheet engraved with a groove topology pattern, conductive feeding points and a feeder line. The power divider is adapted to divide a baseband signal into a plurality of weighted signals and then transmit the weighted signals to the antenna units arranged in an array via the conductive feeding points respectively. By arraying the antenna units and using the beam forming method, the directionality of the antenna can be designed as needed through phase superposition between the antenna units; and then, a reflective metal plate is provided on the back side of the antenna so that a back lobe of the antenna is compressed. In this way, the miniaturized antenna array can obtain a high directionality.

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 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.
