About
The Multiple-beam Feed is a critical component of a mirror antenna system. Its primary purpose is to facilitate the formation of narrow beams, which are directed towards a specified servicing area. This capability is essential for enhancing the signal strength for designated subscribers, particularly in satellite communication applications. The feed operates in the Ka and Q frequency bands and is constructed from materials such as aluminium and brass. The internal channels feature a mechanical operation roughness ranging from Ra 0.63 to 1.25, and are coated with gold or silver to optimize performance. It can accommodate up to 28 radiators, allowing for versatile beamforming configurations. When integrated into an offset mirror antenna, this type of feed significantly improves the efficiency and coverage of communication systems.
