The invention provides an embedded smart skin antenna which is formed by an optical fiber sensing network layer (2), a reconfigurable sub array (3), a thin film TR sub array (4), a reconfigurable feed network (5), and a control and function maintenance module (6). The optical fiber sensing network layer and the reconfigurable sub array are integrated as a whole, are sequentially and parallelly arranged with the thin film TR sub array (4) and the reconfigurable feed network in a laminated manner, and are jointly in parallel connection with the control and function maintenance module at the end. The control and function maintenance module, according to a user demand of a terminal main control device (7), sends a control instruction to the reconfigurable sub array, the thin film TR sub array, and the reconfigurable feed network; the working condition self-diagnosis of the embedded smart skin antenna and the electrical performance reconfiguration of the antenna are realized; the electric performance of the embedded smart skin antenna is ensured; and the defect that, after the sub array is partially damaged, a conventional antenna array is degraded in performance or cannot be reused is avoided.
