Problems solved by technology

However, the proposed radome is a planar structure, which does not consider the interaction between the conformal structure of the radome and electromagnetic waves, and the radome with the above-mentioned planar structure does not realize the physical protection of the antenna, and does not have real practicability

Abstract

The invention provides a triangular pyramid-shaped metasurface antenna cover with a wave beam calibration function, and aims to protect an antenna by a traditional antenna cover electromagnetic windowand improve antenna gain. The metasurface antenna cover comprises a triangular pyramid spliced by three metasurface structures, so that the physical strength and mechanical bearing of the antenna cover are ensured; the metasurface structure adopts a plurality of layers of isosceles right-angled triangular dielectric plates which are mutually stacked; metal patches are printed on the inner surfaces of the dielectric plates of the odd layer from inside to outside, and cross-shaped metal patches are printed on the outer surfaces; and metal patches are printed on the outer side surfaces of the dielectric plates of the even layer. The antenna needs to be arranged on the connecting line of the vertex of the triangular pyramid and the midpoint of the bottom surface, and by calculating the distance from the antenna to each metal patch on the inner surface of the antenna cover and the emergent phase, the calibration function of the emergent waves is realized, and the antenna gain is remarkablyimproved. The metasurface antenna cover can be applied to the field of wireless communication.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a metasurface radome, in particular to a triangular pyramid-shaped metasurface radome with a beam calibration function, which can be used in the field of wireless communication. technical background [0002] A radome is a covering made of natural or man-made dielectric material that creates a specially shaped electromagnetic window. Metasurface is a new type of synthetic electromagnetic material, which is composed of a substrate made of non-metallic materials and multiple artificial microstructures printed on the surface of the substrate or embedded in the substrate. [0003] The traditional radome is required to ensure the stable and normal operation of the antenna, and has the characteristics of wind and sand resistance, high temperature resistance, and high-efficiency wave transmission. However, with the development of technology, people hope to endow the radome with more func...
