Embodiment Construction

[0029] Metamaterial is a new type of material with artificial microstructure 402 as the basic unit, which is spatially arranged in a specific way and has special electromagnetic response, including the artificial microstructure 402 and the substrate 401 on which the artificial microstructure is attached. The artificial microstructure 402 is a planar structure or a three-dimensional structure composed of at least one metal wire. A plurality of artificial microstructures 402 are arranged in an array on the substrate 401. The portion occupied by each artificial microstructure 402 and the substrate 401 attached to it is is a metamaterial unit. The substrate 401 can be any material different from the artificial microstructure 402. The superposition of these two materials makes each metamaterial unit produce an equivalent permittivity and magnetic permeability. These two physical parameters correspond to the metamaterial unit respectively. Electric field response and magnetic field ...

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.

Description

technical field [0001] The invention relates to the field of antennas, and more specifically, to an antenna based on metamaterials and a method for generating working wavelengths of metamaterial panels. Background technique [0002] In conventional optical devices, a lens can make the spherical wave radiated by a point light source located at the focal point of the lens become a plane wave after being refracted by the lens. The lens antenna is composed of a lens and a radiator placed on the focal point of the lens. Using the characteristics of lens convergence, the electromagnetic wave radiated by the radiator is converged by the lens and then emitted. This antenna has strong directivity. [0003] At present, the convergence of the lens is realized by the refraction of the spherical shape of the lens, such as figure 1 As shown, the spherical wave emitted by the radiator 30 is converged by the spherical lens 40 and then emitted as a plane wave. In the process of implementin...
