Abstract
A front feed satellite television antenna includes a metamaterial panel. The metamaterial panel includes a core layer and a reflective panel. The core layer includes a core layer lamella which further includes a circular area and multiple annular areas distributed around the circular area. Within the circular area and the annular areas, refractive indexes are identical at a same radius, and within the respective areas, the refractive indexes decrease gradually as radius increases. The minimum refractive index of the circular area is less than the maximum the refractive index of the annular area adjacent thereto. For two adjacent annular areas, the minimum refractive index of the annular area at the inner side is less than the maximum refractive indexes of the annular area at the outer side. The metamaterial panel can replace conventional parabolic antenna, thus facilitating manufacturing and processing, and further reducing costs.
