The client developed a novel deployable Ka/Ku- band small satellite antenna system with a 1-meter aperture mesh reflector. The new satellite could be used for communication or radar instruments and offered significant benefits over current technology.
Secant Group faced several challenges with this project. The highly compact nature of the product and very small diameter reflector would require an antenna mesh design with a high degree of surface accuracy. Secant Group would need to determine the best material to use and then engineer an antenna mesh with a high number of openings per inch. The mesh needed to have sufficient mechanical stiffness properties to allow for deployment of a parabolic convex or concave shaped reflector. Also, the mesh had to perform at or above Ka band frequency.
