Embodiment Construction
[0043] The present invention relates to a metamaterial satellite antenna, such as Figure 10 , Figure 11 As shown, it includes a feed source 3 , a metamaterial plate 100 , a plate support rod 5 , a fastening frame 8 , and a sliding rod 7 . The plate strut 5 is L-shaped, one end is fixedly connected to the feed source 3 , and the straight section of the other end is fixedly connected to the metamaterial plate 100 in parallel, so that the feed source 3 faces the metamaterial plate 100 .
[0044] Install the flat support rod 5 to the fastening frame 8 on the wall, and the fastening frame 8 is fixed to the wall by the long rod screw 6. Of course, other methods such as hinged with the wall, pasted, bound, welded, etc. can also be used. The method is fixed to the wall, which will not be repeated in this article.
[0045] like figure 1 , figure 2 As shown, one end of the fastening frame 8 is hinged to the L-shaped corner of the flat-plate strut 5, and the other end is hinged to...

The invention discloses a metamaterial satellite antenna. The metamaterial satellite antenna comprises a feed source, a reflection plate, a flat plate supporting rod with one end fixedly connected with the reflection plate and the other end fixedly connected with the feed source, and a fastening frame for mounting the flat plate supporting rod to a wall, wherein one end of the fastening frame is hinged with one point on the flat plate supporting rod; the other end of the fastening frame is hinged with one end of a sliding rod; the other end of the sliding rod moves in the axial direction of the flat plate supporting rod through a limiting structure; the reflection plate is a metamaterial plane reflection plate; the metamaterial plane reflection plate comprises a core layer and a reflection layer arranged on one side surface of the core layer; the core layer comprises one core layer sheet layer or multiple same core layer sheet layers; each of the core layer sheet layers comprises a sheet-shaped first base material and a plurality of first artificial microstructures arranged on the first base material; and the refractive index distribution of single core layer meets the specific formula. The traditional parabolic antenna is replaced with the sheet-shaped reflection plate, and the metamaterial satellite antenna is easy to manufacture and is light and thin in structure. The invention further provides a satellite receiving system with the metamaterial satellite antenna.
Description
technical field [0001] The invention relates to the field of communication, more specifically, to a supermaterial satellite antenna and a satellite receiving system. Background technique [0002] The traditional satellite receiving system is a satellite ground receiving station composed of a parabolic reflector, a feed source, a tuner, and a satellite receiver. The parabolic reflector is responsible for reflecting the satellite signal into the feed and LNB located at the focal point. The feed source is a horn set at the focal point of the parabolic reflector to collect satellite signals, also known as a corrugated horn. There are two main functions: one is to collect the electromagnetic wave signal received by the antenna, transform it into a signal voltage, and supply it to the tuner. The second is to perform polarization conversion on the received electromagnetic waves. The high-frequency head LNB (also known as the frequency reducer) is to reduce the frequency and ampl...
