Abstract

The invention relates to an array lens, a lens antenna and electronic equipment. The array lens comprises a plurality of first dielectric layers; a plurality of layers of first array structures, wherein the first array structures and the first dielectric layers are alternately arranged in a stacked mode in the first direction, each layer of first array structure comprises one or more first array units arranged in an array mode, and multiple first array units located at the same relative position in the layers of first array structures are coaxially arranged in the first direction; in the firstarray structure comprising a plurality of first array units, at least two first array units have gradually changed array unit sizes in the array direction, or / and at least two layers in the layers offirst array structures have gradually changed number of first array units in the first direction, or / and at least two layers in the multiple layers of first array structures have gradually changed number of first array units in the second direction. The array lens structure achieves the convergence effect on electromagnetic wave beams, and the array lens is short in focal length, small in size and beneficial to miniaturization.

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 spherical or cylindrical waves from point or line sources 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 can be adjusted to obtain a plane wavefront on the radiation aperture. A general lens antenna usually requires a large focal length, is bulky and heavy, which 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 lens antenna and are small in size, which is beneficial to the mini...
