Embodiment Construction

[0025] "Metamaterial" refers to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have. Through the orderly design of the structure on the key physical scale of the material, the limitation of some apparent natural laws can be broken through, so as to obtain the supernormal material function beyond the ordinary nature inherent in nature.

[0026] Three important features of "metamaterials":

[0027] (1) "Metamaterials" are usually composite materials with novel artificial structures;

[0028] (2) "Metamaterials" have extraordinary physical properties (often not available in natural materials);

[0029] (3) The properties of "metamaterials" are jointly determined by the intrinsic properties of the constituent materials and the artificial microstructures in them.

[0030] see figure 1 , Embodiment 1 of the present invention, an arrayed metamaterial antenna, comprising: a metamaterial 10 and a metam...

Abstract

The invention discloses an array-type metamaterial antenna. The antenna comprises at least two or more metamaterials. The each metamaterial arranges regularly or arranges randomly. A modulation mode of the each metamaterial to an electromagnetic wave is different. The metamaterial comprises a base material and a plurality of artificial microstructures which are attached to the base material. According to the array-type metamaterial antenna of the invention, through designing electromagnetic space distribution of the metamaterial, the desired modulation result distribution of the antenna can be obtained. A volume is small. The antenna does not occupy too much space. The antenna is simple and easy to realize. Cost is low. It does not depend on the kinds and the shapes of the antenna.

Description

technical field [0001] The invention belongs to the field of metamaterials, and in particular relates to an array type metamaterial antenna. Background technique [0002] The antenna is an important component for sending and receiving electromagnetic wave energy in wireless transmission, allowing users to smoothly use the wireless communication system for information transmission without being restricted by terrain. At present, antennas used in various products have different design methods and materials. Choosing an appropriate antenna can help improve transmission characteristics and reduce production costs. [0003] It is known in the prior art to use an array antenna for transmitting and receiving electromagnetic wave signals. The array antenna of the prior art includes a plurality of antenna parts from which the beams radiated are overlapped to obtain directivity and are required to have a high principal lobe gain, and sufficiently low sidelobe levels to avoid interfe...
