Problems solved by technology

In this system, when the antenna is scanning the beam, it is necessary to set up an azimuth-elevation two-dimensional mount for the antenna to realize the two-dimensional scanning of the beam. This method requires a large servo control power. When performing fast beam pointing , with no apparent advantage

Abstract

The invention discloses a Luneberg lens antenna, and belongs to the technical field of antennas. The Luneberg lens antenna comprises an antenna support and an antenna body, wherein the antenna body is arranged on the antenna support and comprises a reflective bottom plate and a semi-spherical lens, the lens is arranged on a reflective surface of the reflective bottom plate, an universal joint is arranged on a back surface of the reflective bottom plate and is arranged at a central position of the lens, a support body and a feeding source are arranged on the antenna support, the position of the feeding source is fixed, the feeding source points to a sphere center of the lens, the antenna body is connected with the support body via the universal joint, and a mechanical structure is also arranged on the antenna support and is used for pushing the antenna body so that the antenna body rotates by taking the universal joint as a center. The Luneberg lens antenna has the characteristics of a novel structure, high tracking capability and low profile, is convenient to use and is an important improvement of the prior art.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a Lunberg lens antenna. Background technique [0002] In electronic information systems, traditional lens antennas can be used to perform beam scanning in a variety of ways, each of which has its own characteristics, specifically as follows: [0003] 1. The feed source moves in two dimensions while the lens does not move. The beam scanning of this method is relatively simple. A mechanical arm that can rotate in azimuth is set on the edge of the bottom plate of the lens. The feed source is mounted on the mechanical arm, and the feed source can move radially along the mechanical arm. When the manipulator and the feeder move in azimuth, azimuth beam scanning can be realized. When the feed source moves along the radial direction of the manipulator, the elevation beam can be scanned. The beam scanning in this way is relatively simple, but the mechanical motion requires two-dimensi...
