Abstract: Disclosed is a Cassegrain microwave antenna, which comprises a radiation source, a first metamaterial panel used for radiating an electromagnetic wave emitted by the radiation source, and a second metamaterial panel having an electromagnetic wave convergence feature and used for converting into plane wave the electromagnetic wave radiated by the first metamaterial panel. 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 Cassegrain microwave antenna to be panel-shaped or any shape as desired, while allowing for reduced thickness, reduced size, and facilitated processing and manufacturing, thus providing beneficial effects of reduced costs and improved gain effect.

CPC classification number: H01Q15/0086
Abstract: The present disclosure relates to a metamaterial for diverging an electromagnetic wave, which comprises at least one metamaterial sheet layer. Refractive indices of the metamaterial sheet layer are distributed in a circular form with a center of the metamaterial sheet layer, and the refractive indices remain unchanged at a same radius and increase gradually with the radius. The present disclosure changes electromagnetic parameters at each point of the metamaterial through punching or by attaching man-made microstructures so that the electromagnetic wave can be diverged after passing through the metamaterial. The metamaterial of the present disclosure features a simple manufacturing process and a low cost, and is easy to be implemented. Moreover, the metamaterial of the present disclosure has small dimensions and does not occupy a large space, so it is easy to miniaturize apparatuses made of the metamaterial of the present disclosure.

Abstract: The present invention relates to a man-made composite material and a man-made composite material antenna. The man-made composite material is disposed in a propagation direction of a plane electromagnetic wave and convert it into a spherical wave. Reverse extensions of the spherical wave intersect at a virtual focus. A line connecting the virtual focus to a point on the second surface of the man-made composite material and a line perpendicular to the man-made composite material form an angle θ therebetween, which uniquely corresponds to a curved surface in the man-made composite material. A set formed by points having the same angle θ forms a boundary of the curved surface to which the angle θ uniquely corresponds. Each point on the curved surface to which the angle θ uniquely corresponds has a same refractive index. Refractive indices of the man-made composite material increase gradually as the angle θ increases.

Abstract: The present invention relates to an antenna based on a metamaterial and a method for generating an operating wavelength of a metamaterial panel. The antenna comprises a radiation source, and a metamaterial panel capable of converging an electromagnetic wave and operating at a first wavelength. The metamaterial panel is adapted to convert the electromagnetic wave radiated from the radiation source into a plane wave and to enable the antenna to simultaneously operate at a second wavelength and a third wavelength which are smaller than the first wavelength and are different multiples of the first wavelength. The present invention further provides a method for generating an operating wavelength of a metamaterial panel for use in the aforesaid antenna. These improve the convergence performance and reduce the volume and size of the antenna.
