Embodiment Construction

[0023] Light, as a kind of electromagnetic wave, when it passes through glass, because the wavelength of light is much larger than the size of atoms, we can use the overall parameters of the glass, such as the refractive index, rather than the detailed parameters of the atoms that make up the glass to describe The response of glass to light. Correspondingly, when studying the response of materials to other electromagnetic waves, the response of any structure in the material whose scale is much smaller than the wavelength of the electromagnetic wave to electromagnetic waves can also be described by the overall parameters of the material, such as the dielectric constant ε and magnetic permeability μ. By designing the structure of each point of the material, the dielectric constant and magnetic permeability of each point of the material are the same or different, so that the overall dielectric constant and magnetic permeability of the material are arranged in a certain order, and ...

Abstract

The invention discloses a metamaterial antenna housing which comprises at least one metamaterial sheet layer. The metamaterial sheet layer comprises a first substrate and a plurality of artificial microstructures, wherein the artificial microstructures are arranged on the first substrate in a period mode, and are identical in size. Each artificial microstructure comprises two first metal branches which are perpendicular to each other in an equally-divided mode, the two ends of each first metal branch are respectively provided with a first metal rectangle, each end point of each first metal branch is perpendicularly arranged on the midpoint of a long edge of each metal rectangle connected with each first metal branch, one end of each second metal branch is perpendicularly arranged on the midpoint of the other long edge of each first metal rectangle, and the other end of each second metal branch is perpendicularly arranged on the midpoint of a long edge of each second metal rectangle. The working frequency band of the metamaterial antenna housing is in the range of 14.3-26.3GHz, wave-transparent efficiency in the working frequency band is quite high, and loss in the working frequency band is low. The metamaterial antenna housing has the band elimination characteristic outside the range of the working frequency band, and can achieve selective wave filtering.

Description

technical field [0001] The invention relates to the technical field of radome, in particular to a metamaterial radome and an antenna system. Background technique [0002] Generally, the antenna system is provided with a radome. The purpose of the radome is to protect the antenna system from wind, rain, snow, sand and solar radiation, so that the performance of the antenna system is relatively stable and reliable. At the same time, it reduces the wear, corrosion and aging of the antenna system and prolongs its service life. However, the radome is an obstacle in front of the antenna, which will absorb and reflect the radiated waves of the antenna, change the free space energy distribution of the antenna, and affect the electrical performance of the antenna to a certain extent. [0003] At present, the materials for making radome are mostly materials with low dielectric constant and loss tangent and high mechanical strength, such as fiberglass, epoxy resin, high molecular pol...
