Embodiment Construction

[0018] Metamaterials are artificial composite structural materials with extraordinary physical properties that natural materials do not have. Through the orderly arrangement of microstructures, the relative permittivity and magnetic permeability of each point in space can be changed. Metamaterials can realize within a certain range the refractive index, impedance, and wave-transmitting properties that ordinary materials cannot possess, so that they can effectively control the propagation characteristics of electromagnetic waves. The metamaterial radome based on the artificial microstructure can change the relative permittivity, refractive index and impedance of the material by adjusting the shape and size of the artificial microstructure, so as to achieve impedance matching with the air to maximize the incident electromagnetic wave. transmission. And the frequency can be selected by adjusting the size of the microstructure, and the corresponding wave-transmitting and filtering...

Abstract

The invention relates to a communication device applied in a moving robot, comprising an antenna and a radome outside the antenna, wherein the radome comprises at least one metamaterial sheet layer, each metamaterial sheet layer comprises a first substrate and a plurality of artificial microstructures of the same size arranged on the first substrate by an array; The artificial microstructure comprises an oral shape structure, wherein the central position of the oral shape structure is provided with a cross-shaped structure, and the middle of each side of the oral shape structure is provided with a corresponding end structure similar to the aforementioned cross-shaped structure. The invention obtains the required electromagnetic response by attaching the artificial microstructure with a specific shape on the substrate, so that the wave transmission performance of the radome based on the metamaterial is enhanced, and the anti-interference ability is increased.
