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 slit units arranged in an array, the slit unit includes a first slit and a second slit surrounding the first slit and spaced apart from the first slit, and at least two layers of the array structure are located at the same relative position. The slot units are arranged coaxially in the first direction; wherein, in the same array structure, a plurality of first slots have a gradually changing relative rotation angle relative to the array direction in at least one array direction; the phase distribution of different frequency bands can be compensated, The ability to converge electromagnetic waves can keep the focal plane of the array lens unchanged in a wider frequency range, greatly reducing the drop in off-focus beam gain, greatly increasing the scanning angle of the lens antenna, and having 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 is 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] Embodiments of the present application provide 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 array l...
