FRONT FEED SATELLITE TELEVISION ANTENNA AND SATELLITE TELEVISION RECEIVER SYSTEM THEREOF

摘要

Disclosed is a front feed satellite television antenna comprising a metamaterial panel arranged behind a feed. The metamaterial panel comprises a core layer and a reflective panel arranged on a lateral surface of the core layer. The core layer comprises at least one core layer lamella. The core layer lamella comprises a sheet-shaped substrate and multiple artificial microstructures arranged on the substrate. Refractive indexes of the core layer lamella are in a circular distribution, the refractive indexes are identical at a same radius, and the refractive indexes decrease gradually as the radius increases. In the front feed satellite television antenna of the present invention, conventional parabolic antenna is replaced by the sheet-shaped metamaterial panel, thus facilitating manufacturing and processing, and further reducing costs. In addition, the present invention also provides a satellite television receiver system having the front feed satellite television antenna.
