The present invention discloses a feed backward satellite dish, comprising a diverging member disposed at the front panel and the meta-material feed, said metamaterial panel comprises a core layer, the core layer comprises at least one core sheet, the the core layer comprises a sheet-like substrate sheet and a plurality of artificial pore structure disposed on the substrate, the refractive index of the core layer sheet is circular profile, and the same refractive index at the same radius as the radius of increase the refractive index decreases. The satellite antenna fed after the present invention, a sheet-like panel metamaterial instead of the traditional parabolic antenna, manufacturing process easier, lower cost. Further, the present invention also provides a satellite television receiving system having the above-described feeding of the satellite antenna.
