An ultralight antenna panel structure made of CFRP thin plate was proposed to realize Space Solar Power Systems. In the proposed antenna structure, thermal deformation occurs due to the difference in the coefficient of thermal expansion and causes negative effects in the antenna system, especially for the thin plate structure. In this study, theoretical analysis was conducted against a thin plate structure with a single antenna patch using the equivalent inclusion method for plates. The results were validated with finite element analysis. Furthermore, sensitivity studies regarding the layer thickness were conducted and a new structure was proposed.
