Abstract

The invention relates to a dielectric lens, a lens antenna and electronic equipment. The dielectric lens comprises a first conductive plate, a second conductive plate, a focusing layer, and a calibration layer. The second conductive plate is arranged parallel to the first conductive plate. The focusing layer includes a first side face and a second side face which are arranged opposite to each other; the first side face is attached to the first conductive plate; the second side face is attached to the second conductive plate; the first side face includes a first curved surface which is raised towards toward one side of the first conductive plate; and the focusing layer is used for converging electromagnetic waves conducted along a first direction. The calibration layer is connected to the focusing layer in the first direction; the calibration layer includes a third side face and a fourth side face which are disposed opposite to each other; the third side face is attached to the first conductive plate; the fourth side face is attached to the second conductive plate; and the third side face includes a second curved surface, which includes at least one convex surface facing one side ofthe first conductive plate. The calibration layer is used for compensating the phase delay provided by the focusing layer. The offset-focus radiation performance can be effectively improved, and thescanning coverage range of the lens antenna is improved.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a dielectric 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. Generally, the lens antenna is spherical, has a large volume, and has a limited scanning angle, which is not conducive to covering a large area. Contents of the invention [0003] Embodiments of the present application provide a dielectric lens, a lens antenna, and electronic equipment, which can effectively improve off-focus radiation performance and achieve greater scanning coverage. [0004] A dielectric lens comprising: [0005] It includes: a first conductive plate, a second conductive plate, arranged parallel to the first conductive plate; a focusing layer, including a fir...
