Problems solved by technology
The parabolic antenna has only one focal point, making it difficult to realize multi-satellite communication with one antenna, and the structure is heavy, which does not take advantage of the spaceborne environment
Phased array antennas can achieve antenna scanning performance, but due to the limitations of their own physical properties, the beam coverage is generally within ±45°, and there are scanning losses and blind spots
In addition, a large number of T / R components in the active phased array make its design and production cost high, making it difficult to apply to the general satellite communication field

The invention discloses a luneberg lens antenna and a space satellite-borne platform. The luneberg lens antenna comprises a luneberg lens, a feed source array and a test platform, the luneberg lens is mounted on the test platform, is of a spherical structure as a whole and is provided with multiple layers of spherical shells and a spherical core, the spherical core is arranged at the central position of the spherical structure, and the inner surface of the spherical shell wraps the outer surface of the adjacent spherical shell; the feed source array comprises a plurality of array feed sources, each feed source is distributed along the outermost spherical shell, and the central axis of each feed source passes through the sphere center of the sphere core; the test platform is used for installing the Luneberg lens and providing elevation rotation and plane rotation for the Luneberg lens. According to the Luneberg lens antenna, the size and weight of the antenna can be effectively reduced through selection of matching materials of the ball core and the multi-layer ball shell structure, meanwhile, the overall performance of the antenna can be guaranteed by aligning the center axis of the feed source array with the center of the ball core, and the Luneberg lens antenna is particularly suitable for a space satellite-borne environment.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to a Lunberg lens antenna and a space satellite-borne platform. Background technique [0002] With the rapid development of satellite communication technology, radar navigation technology, aerospace communication, telemetry and remote sensing and other technologies, antennas used in various occasions have put forward different special requirements. Multi-target tracking antennas require the antenna itself to have high directional performance, fast tracking speed in a wide range, and small beam delay; ground station satellite communications require antennas with broadband; digital satellite antennas require antennas with one-line multi-satellite functions; high-efficiency and low-cost multi-beam antennas are required in fields such as telemetry and remote sensing and automotive anti-collision radar. [0003] There are two types of multi-beam antennas commonly used at present, which...
