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 an antenna device used in a moving robot, and the device comprises an antenna and a radome on the outside of the antenna, the radome comprises at least one metamaterial sheetlayer, each metamaterial sheet layer comprises a first substrate and a plurality of man-made microstructures of the same size arranged in an array on the first substrate. The artificial microstructurecomprises an orifice structure, a cross-shaped structure is arranged at the center of the orifice structure, and a corresponding end structure similar to the cross-shaped structure is arranged at themiddle of each side of the orifice structure. The invention obtains the required electromagnetic response by attaching the man-made microstructure with a specific shape to the substrate, so that thewave transmission performance of the metamaterial-based radome is enhanced and the stability capability is increased.
