Abstract
The present invention discloses a Cassegrain satellite television antenna comprising a metamaterial plate. The metamaterial plate comprises a core layer. The core layer comprises core sublayers. Each core sublayer comprises a circular area and a plurality of annuli distributed around the circular area. According to the Cassegrain satellite television antenna of the present invention, the traditional parabolic antenna is replaced with a sheet-like metamaterial plate which is easier to process and has a lower cost. In addition, the present invention also provides a satellite television receiving system equipped with the above-mentioned Cassegrain satellite television antenna.
