Abstract: Disclosed is an offset feed satellite television antenna comprising a metamaterial panel (100) arranged behind a feed (1). The metamaterial panel (100) comprises a core layer (10) and a reflective panel (200) arranged on a lateral surface of the core layer (10). The core layer (10) comprises at least one core layer lamella (11). The core layer lamella (11) can be divided into multiple belt areas on the basis of refractive indexes. With a fixed point as a center, the refractive indexes on the multiple belt areas are identical at a same radius, while the refractive indexes on each belt area decrease gradually as the radius increases. For two adjacent belt areas, the minimum value of the refractive indexes of the inner belt area is less than the maximum value of the refractive indexes of the outer belt area. A connection between the center and the feed (1) is perpendicular to the core layer lamella (11), while the center does not overlap the center of the core layer lamella (11). In addition, the present invention also provides a satellite television receiver system having the offset feed satellite television antenna. The present invention allows for facilitated manufacturing and processing, and for further reduced costs.
