Phase correction sticker on reflector of antenna and reflector antenna

Abstract

The invention relates to a phase correction sticker on a reflector of an antenna, which comprises a first base plate, a second base plate and a plurality of artificial microstructures arranged between the first and second base plates. The artificial microstructures are wires made of conductive materials. The first and second base plates are flexible. The refractive index of the phase correction sticker on the reflector of the antenna is reasonably designed, so that emergent electromagnetic wave reflected by the reflector of the antenna attached with the phase correction sticker on the reflector of the antenna has a leveled equiphase surface. According to the phase correction sticker on the reflector of the antenna provided by the invention, the refractive index distribution is arranged inside the phase correction sticker, so that the phase correction sticker on the reflector of the antenna is attached to conventional reflectors to correct the emergent phase from the surface of the reflector and improve the phase error brought by installation or process, so that a leveled emergent equiphase surface is obtained, and further the far field performance (such as higher gain) of the antenna is improved.

Description

technical field [0001] The invention relates to the field of metamaterials, more specifically, to a phase correction film on an antenna reflection surface and a reflection surface antenna. Background technique [0002] The parabolic reflector antenna is an important part of electronic equipment such as radar and communication. The surface accuracy of the antenna reflector is the main factor affecting the electrical performance of the antenna such as gain. At present, with the increase of the antenna aperture and the increase of the operating frequency, the requirements for the accuracy of the antenna reflector are also getting higher and higher. The reflective surface of a large parabolic antenna is often assembled from dozens or even hundreds of reflective surfaces, so the installation and adjustment level of the antenna panel becomes one of the main factors affecting the accuracy of the antenna reflective surface. In the past, the traditional method was that the assembler...
