Embodiment Construction

[0040] Such as Figures 1 to 2 As shown, the antenna reflective surface phase correction film TM according to the present invention includes a first substrate 1, a second substrate 2 and a plurality of artificial microstructures 3 arranged between the first substrate 1 and the second substrate 2, the artificial microstructures Structure 3 is a thread made of conductive material, the first substrate 1 and the second substrate 2 are flexible substrates, and the refractive index distribution of the phase correction film TM on the antenna reflective surface is reasonably designed so that electromagnetic waves pass through the antenna reflective surface phase After being reflected by the antenna reflective surface FS of the bit correction film, the outgoing electromagnetic wave has a flat equi-phase surface.

[0041] The flexible substrate of the present invention is the polyimide or polyester film used in the traditional flexible circuit board (FPC). The artificial microstructure...

Abstract

The present invention relates to an antenna reflector phase correction film and a reflector antenna. The antenna reflector phase correction film includes a first substrate, a second substrate, and multiple artificial microstructures disposed between the first substrate and the second substrate, the artificial microstructures are wires made of electrically conductive materials, and an electromagnetic wave, emergent after being reflected by an antenna reflector attached with the antenna reflector phase correction film, has an equiphase surface. According to the present invention, the antenna reflector phase correction film has specific refractive index distribution internally, so that a surface emergent phase of a reflector can be corrected after attaching onto a surface of a conventional reflector, a phase error caused due to installation or processing is improved, a complete flat emergent equiphase is obtained, and then a far-field performance (such as a higher gain) 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...
