Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] The present invention firstly provides a reflective surface of a magnesium alloy satellite antenna. The reflective surface of the magnesium alloy satellite antenna adopts a structure in which a main reflective surface and a supporting structure are combined into one, and the overall antenna is in a box structure. like Figure 1~Figure 3 As shown, the satellite antenna reflection surface provided by the embodiment of the present invention includes an intermediate body 1 and a plurality of sectors 2, the intermediate body 1 is located at the center, and has a cylindrical structure, also called a box structure; the sector 2 are distributed in the circumferential direction of the intermediate body 1, forming a circular reflective surface projected. The intermediate body and each sector 2 can be integrally formed by casting.

Abstract

The invention provides a magnesium alloy satellite antenna reflection surface, which belongs to the technical field of satellite antennas. The reflective surface of the satellite antenna adopts an integrated molding structure, and the overall antenna is a box structure; the reflective surface of the satellite antenna includes an intermediate body and a plurality of sectors, and the intermediate body is located in the center and has a cylindrical box structure; The fan is distributed in the circumferential direction of the intermediate body, forming a circular reflection surface; the front surface of the fan is a smooth arc surface, and the rear surface is a support structure; the support structure includes radial ribs, axial Ribs and square ribs. The invention has the advantages of high precision, stable signal reception, light weight, good anti-aging performance and not easily deformed.

Description

technical field [0001] The invention belongs to the technical field of satellite antennas, and in particular relates to a magnesium alloy satellite antenna reflection surface. Background technique [0002] The reflective surface of the antenna refers to the conductive curved surface or plane used to reflect the electromagnetic waves emitted by the feed source in a certain direction according to certain requirements in the surface antenna to enhance the emission effect. When used for reception, it can enhance the strength of the received signal and improve the reception Effect, referred to as reflective surface. The main body of most satellite antennas is a parabolic structure, but there are also some multi-focus antennas that are composed of spherical and parabolic surfaces, and the received satellite signals are concentrated to the focal point through the reflection of the parabolic antenna. At present, commonly used reflective surfaces are made of materials such as glass ...
