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 permeability. These two physical parameters correspond to the Electric field response and magnetic field response. The characteristics of the met...

Abstract

The invention relates to an antenna based a meta-material and a method for generating working wavelengths of a meta-material panel. The antenna comprises a radiation source and a meta-material panel which has an electromagnetic wave gathering function and works at a first wavelength, wherein the meta-material panel is used for converting electromagnetic waves emitted by the radiation source into planar waves and running the antenna at a second wavelength and a third wavelength which are smaller than the first wavelength and are in different multiple relations with the first wavelength simultaneously. The invention further provides a method for generating a working wavelength of the meta-material panel of the antenna. The method comprises the following steps of: acquiring a numerical valuem3 / m2 of the ratio lambda3 / lambda2 of the third wavelength lambda3 to the second lambda2 in a preset error range; computing a minimum common multiple m1 of m2 and m3; and generating a working wavelength lambda1 of the meta-material panel, wherein lambda1=lambda2 (m1 / m2) or lambda1=lambda3 (m1 / m3). The working wavelength of the meta-material panel is designed, so that the antenna can work at different wavelengths simultaneously; and the electromagnetic waves of the radiation source are converted into planar waves, so that gathering performance is enhanced, and the volume and size of the antenna are reduced.

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...
