NASA Jet Propulsion Laboratory has baselined a four frequency telecommunication system for the CRAF and Cassini spacecraft antenna subsystems. This design requires the design and development of a Frequency Selective Surface (FSS) subreflector to be integrated into the High gain Antenna Subsystem. The FSS will be able to multiplex S, X, Ku, and Ka frequency band wavelengths. The FSS design incorporates a periodic array of conducting elements on a Kevlar/Polymer composite structure. The design requires the use of well characterized, low dielectric composite materials that are both mechanically and electrically stable over a broad temperature range and to be able to survive in a deep space environment. This work will discuss the development, mechanical and RF electrical testing of two alternative designs as a flat panel design optimization and the status of a full scale RF model prototype.
