Abstract

The invention relates to an array lens, a lens antenna and electronic equipment, and the array lens comprises an array lens which comprises a plurality of first dielectric layers; a plurality of layers of first array structures, wherein the first array structure and the first dielectric layers are alternately arranged in a stacked mode in the first direction, each layer of first array structure comprises multiple array units arranged in an array mode, and the array units located at the same relative position in the layers of first array structures are coaxially arranged in the first direction;wherein the plurality of array units located at the same relative position and the corresponding first dielectric layers jointly form a waveguide structure, and at least two waveguide structures havegradually changed array unit sizes in the array direction of the array units; when electromagnetic waves are incident to the array lens in the first direction, the electromagnetic waves are propagated along the edge of the waveguide structure, the array lens is used for achieving the convergence effect on electromagnetic wave beams, the focal length of the array lens is short, the size is small,and miniaturization of the lens antenna is facilitated.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to an array lens, a lens antenna and electronic equipment. Background technique [0002] Lens antenna is an antenna that can convert point or line source spherical or cylindrical waves into plane waves through electromagnetic waves to obtain pencil-shaped, fan-shaped or other shaped beams. By properly designing the surface shape and refractive index of the lens, the phase velocity of the electromagnetic wave is adjusted to obtain a plane wavefront on the radiation aperture. A general lens antenna usually requires a large focal length, is bulky and heavy, and is not conducive to the miniaturization of the antenna. Contents of the invention [0003] Embodiments of the present application provide an array lens, a lens antenna, and electronic equipment, which can shorten the focal length of the array lens and have a small size, which is beneficial to the miniaturization of...
