Summary: 
We proposed and analyzed a fiber-reinforced ceramic (FRC) composite for a protection layer on top of an antenna mounted on the outer surface of aircraft. The manufactured FRC is a single-layered flat construct. To analyze the performance of the FRC, we extracted the material constant using the transmission/reflection (T/R) method. We described the relation between the pressure and strength of the FRC radome with respect to mechanical properties and analyzed the insertion loss with respect to electrical properties. We evaluated the characteristics of the FRC radome in conjunction with the horn antenna and showed that the analytic results for the FRC radome agree with the experiment results.
