Abstract

The invention discloses a reflector antenna assembly with a flat-top directional diagram, the front surface of a reflector antenna is a reflector, the reflector is a paraboloid, and the paraboloid comprises a central reflection area and an edge reflection area; the central reflection area is circular, the edge reflection area is annular, and the inner periphery of the edge reflection area is connected with the outer periphery of the central reflection area; the connecting edge of the central reflection area and the edge reflection area has a depth difference, and the depth difference is used for enabling the reflection surface to form a wave beam with a flat-top directional diagram; the antenna assembly can be formed through a small number of parts, the complexity of the antenna assembly and the debugging difficulty of the antenna assembly can be reduced, the reflecting surface of the paraboloid-shaped reflecting surface antenna is divided into the central reflecting area and the edge reflecting area, the surface of the central reflecting area and the surface of the edge reflecting area have the depth difference, a wave beam with a flat-topped pattern characteristic can be formed through the reflector antenna, and multiple satellites can be tracked at the same time.

Description

technical field [0001] The invention belongs to the technical field of reflector antennas, in particular to a reflector antenna assembly with a flat-top pattern. Background technique [0002] The reflective surface antenna assembly is an antenna that uses various components and a metal reflective surface to form a predetermined beam. The gain is generally higher than that of a wire antenna, and the higher the operating frequency and the larger the aperture size of the reflector, the higher the gain of the antenna. It is widely used in satellite communication, microwave communication, radar, remote sensing, and bioelectronic technology. [0003] Common reflector antenna assemblies are usually complex in structure and require a large number of parts for assembly, while the signal receiving and receiving accuracy of the antenna assembly is often affected by assembly, and the increase in the number of parts may reduce the antenna accuracy and increase the difficulty of debuggin...
