Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] As a kind of electromagnetic wave, when light passes through glass, because the wavelength of light (400-700 nanometers) is much larger than the size of atoms (0.1 nanometers), we can use the overall parameters of the glass (such as refractive index) instead of composition The glass's atomically detailed parameters describe the glass's response to light. Correspondingly, when studying the response of materials to other electromagnetic waves such as micr...

Abstract

The embodiment of the invention discloses a metamaterial plate, a reflector antenna system and an electromagnetic wave reflection regulating method. According to the electromagnetic wave reflection regulating method, first, the phase distribution of electromagnetic waves reaching the surface of the metamaterial plate is obtained according to rules of electromagnetic wave transmission of a feed source; then, attribute parameters of at least one metal micro structure on the metamaterial plate are regulated, and therefore emergent phases of the electromagnetic waves reflected by the surface of the metamaterial plate are equal. The purpose that antennas are ultrathin is achieved, and space is saved. In addition, the deflection problem of incidence of the electromagnetic waves of large angles further is relieved, and energy radiant efficiency is improved.

Description

technical field [0001] The invention relates to antenna technology, in particular to a metamaterial plate, a reflection surface antenna system and an electromagnetic wave reflection adjustment method. Background technique [0002] Compared with the positive feed antenna, the installation position of the feed source and the tuner of the offset feed antenna is not on a straight line perpendicular to the central section of the antenna and passing through the center of the antenna. Therefore, the offset feed antenna has no influence of the feed source shadow. Under the premise of the same antenna area, processing accuracy and receiving frequency, the gain of the offset feed antenna is greater than that of the forward feed antenna. But today's common microwave antenna systems, no matter the forward-fed antenna or the bias-fed antenna, are all the cross-sections of the rotating paraboloid, but the intercepting positions are different. The forward feed antenna is the part of the c...
