METASURFACE COATING, RADOME ASSEMBLY AND ARRAY ANTENNA

WIPO Patent Application WO/2023/225879

A1

The present application relates to the technical field of terminals. Disclosed are a metasurface coating, a radome assembly and an array antenna. The array antenna comprises a radiation array and a metasurface coating, wherein the radiation array comprises at least two radiation array elements; and the metasurface coating comprises a substrate and a resonant unit provided on the substrate, the metasurface coating covers radiation ends of the radiation array elements, and the surface of the substrate intersects a radiation direction of the radiation array. In the array antenna, a sidelobe level of an original array antenna is cancelled and suppressed by means of a metasurface coating, and a pattern of the array antenna is adjusted by means of the electromagnetic properties of a substrate, and a resonant unit, thereby realizing the low sidelobe processing of the array antenna. The metasurface coating added in the array antenna has a relatively low installation difficulty, and can be directly applied to an existing array antenna which has been built. The array antenna has a high integration level and a compact structure.
