The inorganic particles filled polymer composites have attracted considerable interests because of their good mechanical properties and tailorable performances by controlling the content of the filler. The polymer composites with high permittivity by introducing high dielectric constant ceramics or conducting nanoparticles into the polymer matrix have shown tremendous application foreground. This review focuses on the progress of inorganic/polymer composites and permeability of composite on the performance of embedded passive devices were also investigated. applications in embedded passive devices in recently years. The design and fabrication of the embedded capacitor,inductor and filter based on the Inorganic/Polymer composite were discussed. The effects of parameters including permittivity and
