It is essential to analyze the electrical characteristics of composite materials, such as Carbon Fiber Reinforced Polymer(CFRP), as their electromagnetic properties change according to the method of fabrication. However, the conventional method cannot be applied to paraboloid-shaped deployable reflector antenna panel. In this paper, we analyze the effect of errors generated by waveguide to coaxial adapter while measuring the reflection characteristics of a curved specimen. Using the proposed structure of the adapter, it is confirmed that the reflection characteristics of a curved specimen can be measured by compensating the effect of error that occurs at the interface between the curved surface and the vertical flange waveguide.
