Spherical lens antenna structure

Abstract

The invention relates to the field of communication equipment and particularly relates to a spherical lens antenna structure. The structure comprises a spherical lens sphere, wherein the lens sphere is provided with an antenna array arranged in a spherical crown shape, and the lens sphere is arranged in a lens antenna cover; the antenna array comprises feed source array units which are annularly arranged around the lens sphere and face different directions; the lens sphere comprises a solid sphere core and a shell wrapping the surface of the sphere core, and the sphere core and the shell are crystalline polymers with different dielectric constants. Aiming at a complex special-shaped scene of a city, by adopting the spherical lens antenna structure, narrow-beam and high-gain extension coverage can be formed, a point-to-surface beam forming capability is achieved, difficult points in city 5G signal coverage are solved, the spherical lens antenna structure is applied to a 5G communication base station, the coverage distance is effectively extended, the layout number of the city 5G base station is reduced, and a scarcity problem of investment of 5G network construction site resources in cities is relieved.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a spherical lens antenna structure. Background technique [0002] With the rapid advancement of 5G communication network construction, the fast and convenient experience brought by 5G network is becoming more and more popular. At the same time, the construction problems of 5G base stations in cities are gradually emerging. It is difficult for base station towers to gain a foothold next to high-rise residential buildings and dense buildings. However, the unavoidable problem is that the residents around the base station are worried about the electromagnetic radiation of wireless communication. Designing a concealed 5G base station is very important for deep coverage in dense buildings and residential areas. Contents of the invention [0003] The purpose of the present invention is to provide a spherical lens antenna structure that can effectively improve the extended covera...

AI Technical Summary

Problems solved by technology

[0005] Aiming at complex and irregular scenes in cities, the spherical lens antenna structure can form narrow beams and high-gain extended coverage. It has the ability to form beams from points to areas, and solve the difficult points in urban 5G signal coverage. It can be used in 5G communications. The base station effectively extends the coverage distance, reduces the layout of 5G base stations in cities, and alleviates the scarcity of site resources for investment in 5G network construction in cities
