Communication device, lens antenna and spherical lens

Abstract

The invention relates to a communication device, a lens antenna and a spherical lens. The spherical lens comprises a dielectric carrier and a plurality of dielectric cones. The plurality of dielectriccones are uniformly arranged on the outer surface of the dielectric carrier. Each dielectric cone is provided with three wall surfaces, and every two of the three wall surfaces are connected to formthree edges with the same shape. An included angle between two surfaces formed by connecting any two edges with the central axis of the dielectric cone is 120 degrees, and the section, perpendicular to the central axis of the dielectric cone, of the dielectric cone is an equilateral triangle. Compared with a traditional mode that dielectrics made of different materials are laminated to adjust anddesign the dielectric filling ratios of different parts, the method has the advantages that a plurality of dielectric cones with the same shape are processed by adopting the same material, and the plurality of dielectric cones are uniformly arranged on the dielectric carrier, so that the manufacturing difficulty can be greatly reduced; the processing precision is high; the assembly is easy; and large-scale mass production can be realized.

Description

Technical field [0001] The present invention relates to the field of antenna technology, in particular to a communication device, a lens antenna and a ball lens. Background technique [0002] With the advancement of the worldwide 5G network plan, while meeting the performance requirements of high gain, low sidelobe, narrow beam, and wide beam coverage, cost requirements must also be considered. Lens antennas must be able to carry large information capacity without Increase its number. Traditionally, Lumber Ball lens technology has the ability to carry multiple antennas and multiple beams. Lumber Ball lenses include multilayer dielectric bodies arranged in order from the inside to the outside. The dielectric materials of the multilayer dielectric bodies are different, and they need to be processed in order. , The process is complicated, the production cost is high, and the assembly efficiency is low. Summary of the invention [0003] Based on this, it is necessary to overcome the...
