Title:
ANTENNA INTENDED FOR SATELLITE COMMUNICATION AND CAPABLE OF TRANSCEIVING MULTIPLE POLARIZED WAVES
Document Type and Number:
WIPO Patent Application WO/2012/121525
Kind Code:
A2
Abstract:
The present invention relates to a polarizer rotating device for multiple polarized wave satellite signals, and to an apparatus for receiving satellite signals comprising the device. The apparatus for receiving satellite signals comprises: a feed horn for receiving a satellite signal; a low-noise block-down converter for processing the signal received by the feed horn; and a skew compensation device which is arranged in the low-noise block-down converter or in the feed horn, and which rotates the low-noise block-down converter or the feed horn to compensate for a skew angle when the satellite signal received by the feed horn is a linear polarized wave. The low-noise block-down converter includes a polarizer rotating device for receiving a linear polarized wave signal and a circular polarized wave signal among the satellite signals. The apparatus for receiving satellite signals of the present invention has a simple structure capable of receiving and processing both linear polarized waves and circular polarized waves.
