Abstract

The invention relates to an array lens, a lens antenna and electronic equipment. The array lens includes multiple dielectric layers; and multiple layers of array structures. The array structures and the dielectric layers are alternately stacked along a first direction. Each layer of the array structure comprises multiple spaced array cells arranged in an array. Each array cell comprises a first conductive sheet and a second conductive sheet surrounding the first conductive sheet, and multiple array cells located at the same relative position in multiple layers of the array structures are coaxially arranged in the first direction, wherein multiple first conductive sheets in the same array structure have gradually varying conductive sheet sizes in the array direction. When the electromagnetic wave is incident on the array lens along the first direction, the array lens can compensate the phase distribution of different frequency bands, converge the electromagnetic wave, keep the focal plane of the array lens unchanged in a wider frequency range, greatly reduce the reduction of the polarization beam gain and greatly improve the scanning angle of the lens antenna.

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...
