About
The Cassegrainian Antenna is an on-board antenna system specifically designed for space applications. Its primary purpose is to form a required servicing area and facilitate signal reception within the C, Ka, and Q frequency bands. The product is flight qualified, ensuring its reliability and performance in the harsh space environment. It features a Cassegrain antenna type, utilizing a paraboloid of rotation cut for the main reflector and a hyperboloid of rotation cut or specially formed polynomial surfaces for the subdish. The feed system can be configured as either a single-beam or multiple-beam horn. The antenna’s overall dimensions are flexible, with the reflector diameter ranging from a minimum of 600 mm to a maximum of 2200 mm. The manufacturer also highlights a technology for manufacturing mirror antennas of a caisson type with reduced reflector surface density, suggesting advanced construction techniques.
