Design and Fabrication of an Reflector Antenna for Satellites Using Carbon Fiber Reinforced-Silicon (CFRS)

This paper presents the design, fabrication, and performance verification of a satellite reflector antenna made of carbon fiber-reinforced silicon (CFRS) material. Electrical measurements of the fabricated CFRS specimens revealed that those coated with Sylgard silicone exhibited higher conductivities and more stable characteristics than those coated with Wacker silicone. At lower frequencies, both coatings exhibited similar conductivities; however, Sylgard’s superiority became evident at higher frequencies. The measured maximum gain of the fabricated CFRS reflector antenna was approximately 30 dBi, closely aligning with simulation results. In addition, the 3 dB beamwidths from measurements and simulations matched, confirming the proper operation of the antenna.
