AI Technical Summary

Technical Problem

Existing lens antennas have problems with narrow vertical beam width, high processing difficulty or high cost in high-capacity communication scenarios. In particular, spherical Luneburg lenses are difficult to process, and the horizontal and vertical radiation patterns of cylindrical lenses are inconsistent.

Method used

A nested component structure is adopted, including a nested body with an annular inclined surface and a tail nested body. By adjusting the dielectric constant and shape, performance similar to that of a spherical Luneburg lens is formed, while the processing process is simplified.

Benefits of technology

The antenna gain is increased, the beam consistency is improved, the structure is simple and easy to process, the cost is low, and the size is smaller at the same diameter, meeting the miniaturization requirements.

Abstract

A lens antenna comprises a nested assembly and a feed source disposed below the nested assembly. The nested assembly comprises at least one first nested body having a first annular inclined surface and a tail nested body embedded within the first nested body. The first annular inclined surface and the tail nested body constitute an active surface of the nested assembly, and the active surface gradually narrows from the first nested body to the tail nested body. This lens antenna has a simple structure, is easy to manufacture, and has consistent horizontal and vertical beams.
