[0039] Such as Figure 1 to Figure 6 As shown, the feed-forward satellite TV antenna according to the present invention includes a diverging element 200 with electromagnetic wave divergence function arranged behind the feed source 1, and a metamaterial panel 100 arranged behind the divergent element 200. The metamaterial panel 100 includes a core The layer 10 and the reflector 200 arranged on one side surface of the core layer 10, the core layer 10 includes at least one core layer sheet layer 11, the core layer sheet layer includes a sheet-like substrate 13 and is arranged on the substrate 13 According to the refractive index distribution, the core layer 11 can be divided into a circular area Y located in the middle position and a plurality of artificial hole structures 12 distributed around the circular area Y and co-centric with the circular area. Annular area (represented by H1, H2, H3, H4, H5 in the figure), the refractive index at the same radius in the circular area Y and...
