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...

The embodiment of the invention discloses a metamaterial plate, a reflection surface antenna system and an electromagnetic wave reflection adjustment method. First, according to the law of the electromagnetic wave emitted by the feed source, the phase distribution of the electromagnetic wave reaching the surface of the metamaterial plate is obtained. Then adjust the attribute parameters of at least one metal microstructure on the metamaterial plate, so that the outgoing phases of the electromagnetic waves reflected from the surface of the metamaterial plate are equal. The ultra-thin antenna is realized, which saves space; in addition, the deflection problem of the incident electromagnetic wave at a large angle is improved, and the energy radiation 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...
