Embodiment Construction

[0041] It should be noted that the features in the various embodiments of the present invention can be combined with each other if there is no clear limitation or conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0042] In order to overcome the shortcomings of antennas in the prior art, the present invention provides a metamaterial antenna enhancement device, which is arranged at the front end of the antenna unit and is used to increase the gain of the antenna unit. The enhancement device includes at least one metamaterial layer. , The metamaterial layer includes a substrate and a conductive geometric structure attached to the substrate.

[0043] Metamaterials use the principle of different refractive indexes of different media. Multiple metal microstructures are set on a uniform material to change the refractive index of the material. The refractive index of the metal microstructure is...

Abstract

The invention discloses a metamaterial antenna reinforcing device, an antenna and an antenna array. The metamaterial antenna reinforcing device is arranged at the front end of an antenna unit, and is used for improving the gain of the antenna unit. The metamaterial antenna reinforcing device comprises at least one metamaterial layer, wherein the metamaterial layer comprises a substrate and a conductive geometric structure, and the conductive geometric structure is attached to the substrate. By adopting the technical scheme, the metamaterial antenna reinforcing device has the advantage that the metamaterial antenna reinforcing device is arranged at the front end of the antenna, and the reinforcing device is provided with at least one metamaterial layer with conductive geometric material, so the gain of a far field can be effectively increased, and the integral property of the antenna is improved.

Description

Technical field [0001] The invention relates to the field of wireless communication, in particular to a metamaterial antenna enhancement device, an antenna, and an antenna array. Background technique [0002] The antenna is a kind of converter that transforms the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. [0003] Commonly used antennas usually include horn antennas, slot antennas, microstrip antennas, dipole antennas and monopole antennas. Take the horn antenna as an example. Its inherent characteristics are strong directivity, bandwidth, and high gain, and it has been perfected and developed. The possibility of improving antenna performance through the horn structure is very small. In order to improve the far-field gain of the horn antenna, the prior art mainly reduces the opening angle of th...
