Abstract

See full text

There are provided a polarizer rotating device and a satellite signal receiving apparatus having the same. The satellite signal receiving apparatus includes a feedhorn that receives a satellite signal; a low noise block down converter that processes the signal received by the feedhorn; a skew compensating device that is provided at the low noise block down converter or the feedhorn and rotates the low noise block down converter or the feedhorn to compensate for a skew angle when the satellite signal received by the feedhorn is a linearly polarized wave; a polarizer that receives a linearly polarized signal and a circularly polarized signal of the satellite signal; and a polarizer rotating device that rotates the polarizer when the satellite signal received by the polarizer is a circularly polarized wave. In such a simple structure, the linearly polarized wave and the circularly polarized wave are all received to be processed.
