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 layers of array structure, the dielectric layer and the array structure are alternately stacked along the first direction; each layer The array structure includes at least two hollow grooves arranged in an array, each of the hollow grooves is provided with a split ring piece, and at least two of the split ring pieces in the same relative position of the at least two array structures are positioned on the first side. Upward coaxial arrangement; wherein, in the same array structure, at least two of the split rings have gradually changing opening sizes in the array direction, which can compensate the phase distribution of different frequency bands, and can converge electromagnetic waves, which can make the The focal plane of the array lens remains unchanged in a wider frequency range, which greatly reduces the drop in off-focus beam gain, greatly increases the scanning angle of the lens antenna, and has 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 ...
