Problems solved by technology

The electromagnetic waves radiated by a general lens antenna at a feed source that is far away from the lens focus cannot be well converged, so that the scanning angle of the lens antenna is limited. The scanning angle is limited, which is not conducive to covering a large area.

Abstract

The application relates to an array lens, a lens antenna and electronic equipment, an array lens medium layer; a two-layer array structure, which is respectively arranged on two opposite sides of the medium layer; wherein, the array structure includes a conductive body, on which there are multiple Hollow grooves set in a three-dimensional array, each hollow groove has a built-in conductive sheet and an open ring sheet surrounding the conductive sheet, and the conductive body, conductive sheet, and open ring sheet are separated from each other. The two hollow grooves are coaxially arranged, and the opening directions of the split ring pieces in the two hollow grooves are opposite. The conductive pieces in the multiple hollow grooves in the same array structure have a gradually changing conductive piece size in the array direction, which can be used for different frequency bands. The phase distribution of the lens antenna is compensated, so that the electromagnetic waves radiated by the feed source far away from the focus can be better converged, greatly reducing the drop in off-focus beam gain, and greatly increasing 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. The electromagnetic waves radiated by a general lens antenna from a feed source that is far away from the lens focus cannot be well converged, so that the scanning angle of the lens antenna is limited and the scanning angle is limited, 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 ...
