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. Such as 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 reflecting surface, and belongs to the technical field of satellite antennas. The satellite antenna reflecting surface is an integrally-formed structure. An antenna is a box structure. The satellite antenna reflecting surface includes an intermediate body and a plurality of fan-shaped surfaces. The intermediate body is located at the center and is a cylindrical box structure. The fan-shaped surfaces are distributed in the circumferential direction of the intermediate body, and form a reflective surface projected in a circular shape. The front surfaces of the fan-shaped surfaces are smooth arc surfaces, and the rear surfaces of the fan-shaped surfaces are configured as a support structure. The support structure includes a radial stiffener, an axial stiffener and a square stiffener. The magnesium alloy satellite antenna reflecting surface has high accuracy, stable signal reception, low weight, and good anti-aging performance andis less likely to deform.

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 ...
