The invention discloses a metamaterial satellite antenna which comprises a signal receiver and a metamaterial flat plate. The metamaterial flat plate is fixed on a wall through a support. The metamaterial flat plate comprises a core layer and a grid-shaped reflecting plate arranged on the rear surface of the core layer. The core layer comprises a substrate and a plurality of artificial microstructures attached to the front surface of the substrate. The grid-shaped reflecting plate is attached to the rear surface of the substrate so that electromagnetic wave transmitted by the satellite converges in the signal receiver after being responded by the metamaterial flat plate. In addition, the sheet-shaped metamaterial flat plate replaces a traditional parabolic antenna, and therefore manufacture and machining are easy, and cost is low. Furthermore, the overall thickness of the metamaterial flat plate is in a millimeter level, and the metamaterial flat plate is thin and light. The invention further provides a satellite receiving system.
Description
technical field [0001] The invention relates to the technical field of communication, and more specifically, to a metamaterial satellite antenna and a satellite antenna receiving system. Background technique [0002] Existing satellite antennas, such as satellite TV receiving antennas, usually use traditional reflector antennas, which are usually parabolic antennas, and the parabolic antenna is responsible for reflecting the received signal to the signal receiver located at the focal point. [0003] When receiving the electromagnetic wave signal from the satellite, the parallel electromagnetic wave (because the distance between the satellite and the earth is quite far, the electromagnetic wave emitted by it can be considered as a plane wave when it reaches the ground) is reflected by the parabolic antenna and converges on the signal receiver. [0004] However, it is difficult to process the curved surface of the reflective surface of the parabolic antenna, and the precision ...
