About
The Mirror Antenna Reflector is a critical component of a mirror antenna system, intended for use in space applications. It is designed to operate across a wide range of frequency bands, including C, Ku, Ka, and Q, which are commonly used in satellite communications. The reflector is constructed from high-performance materials such as carbon fiber-reinforced plastic, beryllium, and titanium, chosen for their strength-to-weight ratio and thermal stability in the harsh space environment. The reflective surface boasts a roughness (Ra) between 0.63 and 1.25, ensuring efficient signal reflection. Forming mandrels are made from Invar or composite materials. For enhanced performance, the reflector features a multi-layer radar-reflective coating, which can be based on aluminum, nichrome, or aluminum oxide, depending on specific requirements. The overall dimensions of the reflector can vary significantly, with a maximum diameter of 2200 mm and a minimum diameter of 180 mm. The product can be optionally mounted on a boom and includes areas for hold-down locks and optical checking elements, facilitating integration and deployment in spacecraft.
