FEED HORN ASSEMBLY OF PARABOLIC ANTENNA FOR MULTIMODE MONOPULSE

摘要

The present invention relates to a technology for designing a feed horn assembly of a parabolic antenna for multimode monopulse satellite tracking. The feed horn assembly includes: a feed horn which is in accordance with a pattern standard and a cross polarized wave standard in a broad band and receives signals; a circular wave guide which generates a basic mode signal (TE11 mode) and a high-mode (TE21 mode) by using a circular polarization signal received by the feed horn; and a high-mode coupler which comprises multiple slots, and generates a signal for tracking based on a signal received from the circular wave guide.
