Abstract

The present application relates to an array lens, a lens antenna and an electronic device. The array lens includes: at least one dielectric layer; at least two array structures, the dielectric layer and the array structure are alternately stacked along the first direction; each layer of the array structure includes a metal body , the metal body is provided with a plurality of hollow grooves arranged in an array, each hollow groove is built with an array unit isolated from the metal body, and the multiple array units with at least two layers of array structures located at the same relative position are aligned in the first direction. Axis setting; wherein, in the same array structure, the array units in multiple hollow slots have a relative rotation angle that gradually changes relative to the array direction in at least one array direction; the phase distribution of different frequency bands can be compensated, and electromagnetic waves can be converged , which can keep the focal plane of the array lens unchanged in a wider frequency range, greatly reduce the decrease in off-focus beam gain, greatly increase the scanning angle of the lens antenna, and have a large coverage.

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 ...
