Abstract

The invention relates to a deformable luneberg lens which comprises a lens body in an ellipsoidal shape. The invention further discloses a deformable luneberg lens antenna. The lens body is ellipsoidal. Compared with a traditional spherical structure, on the premise that other structures of the lens body are not changed, it is ensured that the performance such as gain is not changed, the size canbe reduced, and therefore application scenes with different widths of wave beams in different directions are met. The beam broadening effect of the deformable lens antenna is obvious, and when the deformable lens antenna serves as a phased array element, the space coverage range of scanning beams is obviously increased.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a deformed Lunberian lens and an antenna. Background technique [0002] The basic shape of a Luneburg lens is a sphere. The Luneburg lens antenna is a lens antenna that focuses electromagnetic waves to a focal point through a dielectric, including a Luneburg lens and a feed placed on the lens. A Lunberg lens sphere is a sphere made of dielectric material that can converge electromagnetic waves coming from all directions to a corresponding point on the lens surface. In the part infinitely close to the surface of the sphere, the dielectric constant of the material is 1, which is the same as that of air; the dielectric constant at the center of the sphere is 2, and the dielectric constant of the sphere from the surface to the center is gradual. . [0003] The radiation pattern of the existing spherical Lunberg lens antenna has the same conical shape in different directions of the...
