摘要:
The present invention relates to a rotation apparatus of the polarizer for a multiple-polarized satellite signals and a satellite signal receiving apparatus included with the apparatus, includes a feedhorn for receiving satellite; a low noise block down converter for processing signals received by the feedhorn; and a skew compensation apparatus, included in the low noise block down converter or feedhorn, for rotating the low noise block down converter or feedhorn to compensate skew angles in the case that the satellite signals received in the feedhorn are the linearly polarized waves, the low noise block down converter includes the rotation apparatus of the polarizer for receiving linearly polarized signals and circularly polarized signals of the satellite signals, thereby to receive and process both of linearly polarized wave and circularly polarized wave by a simple structure.
