Abstract

The invention relates to an array lens, a lens antenna and electronic equipment. The array lens comprises at least one dielectric layer, at least two layers of array structures, wherein the dielectriclayers and the array structures are alternately stacked along a first direction; wherein each layer of array structure comprises a metal body, a plurality of hollowed-out grooves formed in an array mode are formed in the metal body, an array unit isolated from the metal body is arranged in each hollowed-out groove, and the multiple array units, located at the same relative position, of at least two layers of array structures are coaxially arranged in the first direction; wherein in the same array structure, the array units in the plurality of hollowed-out grooves have relative rotation angleswhich are gradually changed relative to the array direction in at least one array direction; phase distribution of different frequency bands can be compensated, electromagnetic waves can be gathered,the focal plane of the array lens can be kept unchanged within a wider frequency range, the decreasing amplitude of offset beam gain is greatly reduced, the scanning angle of a lens antenna is greatly increased, and the coverage range is large.

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 can be adjusted to obtain a plane wavefront on the radiation aperture. General lens antennas usually have a limited scanning angle, which is not conducive to covering a large area. Contents of the invention [0003] The embodiment of the present application provides an array lens, a lens antenna and electronic equipment, which can greatly reduce the drop in off-focus beam gain, improve the scanning angle of the lens antenna, and have a large coverage. [0004] An ...
