Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] The principle of the present invention is: if the electromagnetic wave at any angle is emitted from a material with a refractive index of 0 to the air medium (with a refractive index of 1), the outgoing direction of the electromagnetic wave will be perpendicular to the material, so that any angle incident on the refracted When an electromagnetic wave in a metamaterial with an index of 0 exits from the metamaterial into an air medium with a refractive index of 1, its outgoing direction will be substantially perpendicular to the metamaterial. Therefore, the electromagnetic wave has changed fro...

Abstract

The invention relates to a patch antenna which is made of metamaterials with a 0 refractive index. The patch antenna comprises two parallel sheets of metamaterials, a feeder line fixing plate, feed source and a fixing structure, wherein the feeder line fixing plate which is parallel to the two sheets of metamaterials is arranged on one side of the two sheets of metamaterials; one side surface of a feed source fixing plate, which is far away from the metamaterials, is provided with the feed source; and the fixing structure is used for connecting and fixing the two sheets of metamaterials and the feeder line fixing plate. The property that a propagation direction of an electromagnetic wave is perpendicular to a surface of a medium wtih a 0 refractive index when the electromagnetic wave reflects from the medium with a 0 refractive index to an air medium with a 1 refractive index is utilized, so that the patch antenna is good in directivity and accordingly high in gain.

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, in particular to a metamaterial patch antenna. 【Background technique】 [0002] Metamaterial is a new type of material with artificial structure as the basic unit and spatially arranged in a specific way, which has special physical and chemical properties that natural materials do not have. Its special properties are not due to the chemical composition of the material itself. Rather, it is determined by the characteristics of its artificial structure. Through careful calculation and design, various materials with special permittivity and magnetic permeability can be artificially produced, such as left-handed materials. Because these materials have some properties that natural materials do not have, metamaterials have broad application prospects. [0003] The special properties of metamaterials depend to a large extent on the key physical scales of the materials. For example, crystals are ordered a...
