Abstract

The present application relates to a dielectric lens, a lens antenna and an electronic device. The dielectric lens includes a first conductive plate and a second conductive plate arranged in parallel with the first conductive plate; a dielectric layer includes a top layer and a bottom layer arranged opposite to each other, The top layer is attached to the first conductive plate, and the bottom layer is attached to the second conductive plate; wherein, the top layer is a first smooth curved surface, and the dielectric layer includes a first gradient area, and the first A gradation area protrudes toward the first conductive plate, and the thickness of the gradation area decreases symmetrically from the center of the first gradation area to the edges on both sides of the first gradation area; the thickness For the distance between the first conductive plate and the second conductive plate, the continuous change of the equivalent refractive index can be achieved, and the radiation efficiency is high.

Description

technical field [0001] The present application relates to the field of antenna technology, and in particular, to a dielectric lens, a lens antenna and an electronic device. Background technique [0002] Lens antenna is an antenna that can convert spherical or cylindrical waves of point or line sources into plane waves through electromagnetic waves to obtain pencil-shaped, sector-shaped or other shaped beams. By appropriately designing the lens surface shape and refractive index, the phase velocity of the electromagnetic wave can be adjusted to obtain a plane wavefront on the radiation aperture. The equivalent refractive index of a general lens antenna can only change discretely, and its radiation efficiency is low. SUMMARY OF THE INVENTION [0003] The embodiments of the present application provide a lens antenna and an electronic device, which can realize continuous change of the equivalent refractive index and have high radiation efficiency. [0004] A dielectric lens,...
