Abstract

The invention discloses a metamaterial satellite antenna which comprises a metamaterial plate and an antenna installing base, wherein the metamaterial plate is arranged on the back of a feed source, the antenna installing base is used for fixing and installing the metamaterial plate on a wall, the metamaterial plate comprises a core layer and a reflecting plate arranged on the rear surface of the core layer, the reflecting plate is in a grid pattern and comprises a plurality of metal sheets with same intervals, the core layer comprises a base plate and a plurality of artificial microstructures attached on the front surface of the base plate, the reflecting plate is attached on the rear surface of the base plate, plane electromagnetic wave generated by the feed source is emitted with an angle with the normal direction of the core layer after the electromagnetic wave penetrated through the metamaterial plate and compared with emitting along the normal direction of the core layer, the minor level of the antenna can be effectively reduced, and a traditional parabolic antenna is replaced by the sheet metamaterial plate, so that manufacture and processing are easier and the cost is lower, the whole thickness of the metamaterial plate is in millimeter level and the metamaterial plate is quite light and thin. The invention further provides a satellite receiving system.

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] Existing satellite antennas, such as satellite TV receiving antennas, usually use a traditional reflector antenna, usually a parabolic antenna, and the parabolic antenna is responsible for reflecting the received signal to the feed source 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 then converged to the feed source. Usually, the corresponding feed source of the parabolic antenna is a horn antenna. [0004] However, it is difficult to process the curved surface of the reflective surface ...
