Embodiment Construction
[0056] like Figure 1 to Figure 5 As shown, it is a structural schematic diagram of an offset feed satellite TV antenna according to the first embodiment of the present invention. The offset feed satellite TV antenna includes a metamaterial panel 100 fixedly attached to the vertical wall NQ, and the metamaterial panel The lower edge of 100 is at the same level as the upper end of the feed source 1, and the metamaterial panel 100 includes a reflective layer 200 with one side surface set against the wall, a core layer 10 set on the other side surface of the reflective layer 200, and another set of the core layer. Impedance matching layer 20 on one side surface. Feed 1 is a traditional corrugated horn, which has different choices depending on the polarization of the TV signal of the satellite. For example, the TV signal of Zhongxing No. The source should be a corrugated horn with dual circular polarization. In addition, in the present invention, the reflective layer is a metal ...
