Abstract

The application relates to an array lens, a lens antenna and an electronic device. The array lens includes a multi-layer dielectric layer; a multi-layer array structure, the array structure and the dielectric layer are alternately stacked along the first direction, and each layer of the array The structure includes a plurality of spaced array units arranged in an array, the array unit includes a first conductive sheet and a second conductive sheet surrounding the first conductive sheet, and multiple layers in the same relative position in the array structure The array units are arranged coaxially in the first direction; wherein, the plurality of first conductive sheets in the same array structure have a gradually changing conductive sheet size in the array direction, when the electromagnetic wave is incident on the array along the first direction When using the lens, the array lens can compensate the phase distribution of different frequency bands, and can converge the electromagnetic waves, which can keep the focal plane of the array lens unchanged in a wider frequency range, greatly reducing the drop in gain of the off-focus beam, and greatly Increase the scan 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...
