About
The Offset Mirror Antenna is an on-board spacecraft antenna designed to form the required servicing area and receive signals within the operating frequency band. It has been in production since 2011 and offers a guaranteed service life of 15 years, with an estimated production/delivery time of 15 months. The antenna has undergone unconditional flight qualification, having flown on spacecraft since launch. It operates across C, Ku, Ka, and Q frequency bands, and is available with reflector types including paraboloid of rotation cut, elliptic paraboloid cut, and contour reflectors. The feed system is a horn type, available in single-beam or multiple-beam configurations. Overall reflector dimensions range from a maximum diameter of 1800 mm to a minimum diameter of 180 mm. The manufacturer notes an efficient manufacturing technology for antennas with complex mechanical interfaces.
