Problems solved by technology

However, the geometrical diffraction theory was used to analyze the radiation characteristics of the antenna, and it was found that the metal strut used to support and fix the secondary side of the antenna has a serious impact on the scattering pattern and the reliability of the connection. and other quality problems
The task of the antenna model with special requirements cannot meet its requirements

Embodiment Construction

[0018] The present invention will be described below in conjunction with specific embodiments:

[0019] The dielectric support cover on the secondary side of the ring-focus antenna in this embodiment has a Φ800×Φ400×600mm thin-walled circular truncated fully enclosed structure.

[0020] The specific manufacturing process is:

[0021] Step 1: According to the external dimensions of the dielectric support cover on the secondary side of the ring-focus antenna to be formed, cast a basic mold.

[0022] Step 2: Paste a film on the outer surface of the basic mold and form a peelable mold after curing. In this way, the peelable mold can be used repeatedly, and the formed peelable mold is the outer film, which well solves the problem of the overall mold release of the large-scale thin-walled secondary surface media support and the product appearance quality problem

[0023] Step 3: Apply a release agent on the inner surface of the peelable mold; use high-performance epoxy resin with high-streng...

Abstract

The invention provides a ring-focus antenna minor face medium supporting cover and a manufacturing method thereof. The medium supporting cover is of a thin-wall circular truncated cone whole sealing structure. The medium material of the medium supporting cover is formed by combination of epoxy resin and a high-strength S glass fiber reinforcement material, and an antioxidant material and an ultraviolet ray absorbing material are also included in the medium material. According to the ring-focus antenna minor face medium supporting cover and the manufacturing method thereof, a traditional antenna minor face metal brace rod is replaced with the antenna minor face medium supporting cover, and by means of the selection of medium material and backstepping design and machining of a forming die, the manufactured antenna minor face medium supporting cover has the advantages that the dielectric property is excellent, rigidity is high, the specific gravity is small, and the outer surface roughness meets requirements of engineering design; a test on a horn and a minor face combined feed source shows that compared with the traditional antenna minor face metal brace rod, the antenna minor face medium supporting cover has the advantages that influence on a scattering directional diagram is small, standing waves are not influenced, and only the radial direction is slightly changed.

Description

Technical field [0001] The invention relates to the technical field of support for the secondary surface of a loop focus antenna, in particular to a dielectric support cover for the secondary side of a loop focus antenna and a preparation method thereof. Background technique [0002] With the rapid development of the aerospace industry, higher and higher requirements are placed on ground-based measurement and control equipment. At this stage, most antenna secondary surfaces are still supported by metal struts, such as figure 1 Shown. Metal parts such as steel plates, steel pipes, aluminum pipes are used, and processed through the process of material preparation → inspection → fitter → inspection → welding → fitter → inspection → coating → inspection → fitter → inspection → welding → inspection → complete set → assembly → inspection. However, the application of geometric diffraction theory to analyze the radiation characteristics of the antenna, and found that the general metal b...
