About
The Double-mirror Ka-band Parabolic Antenna is engineered for space applications, specifically for forming required servicing areas, radiating signals within the operating frequency band, and forming the necessary polarization of the radiated signals. This product has undergone flight qualification, ensuring its suitability for the harsh space environment. It features a reflector aperture diameter of 1800 mm and a hyperbolical subdish diameter of 140 mm. The reflector is constructed from CFRP polymeric composite material, contributing to its relatively low mass of 10.5 kg. The antenna is designed to maintain a high degree of precision, with an rms deviation of the reflector reflecting surface profile not exceeding 0.3 mm, taking into account utilization factors. Its primary function is to facilitate communication in the 20 GHz frequency band.
