Description

Technical Field

[0001] The utility model relates to the technical field of satellite signal capture, in particular to a long-wave signal reflection panel applied to a satellite antenna and a satellite antenna. Background Art

[0002] The signal receiving panel of a satellite antenna is usually designed as a spherical surface, which is responsible for reflecting the satellite signal to the feed and high-frequency head at the focus. The function of a satellite antenna is to collect weak signals transmitted by the satellite and remove noise as much as possible. Most antennas are usually spherical, and some multi-focus antennas are a combination of spherical and parabolic surfaces. The satellite signal is reflected by the parabolic antenna and concentrated at its focus.

[0003] According to different application scenarios, the signal reflection panels of satellite antennas have various specifications. Panels that receive shortwave signals have higher requirements for panel precision, but due to the characteristics of shortwave signals, such signal reflection panels are not made of high-precision mold stamping or carbon fiber. In addition, such shortwave signal panels can meet the requirements by selecting small-area signal reflection panels.

[0004] As for the signal reflection panel that receives long-wave signals, due to the characteristics of long-wave signals, in order to ensure that the antenna can receive enough signals, the satellite antennas in the prior art mostly use signal reflection panels with larger areas. This signal reflection panel has certain difficulties in the transportation process. In order to solve the transportation problem, Chinese utility model patent No. CN216903361U provides a satellite antenna reflection surface that can realize on-site assembly of satellite panels. However, in actual use, this type of reflection panel still has the problem of poor wind resistance during the process of assembly and use. Utility Model Content
