The　lead-free　Ca(SnxTi1-x)O3,　(0　＜　x　＜　0.8)　sample　has　been　successfully　prepared　through　the　ball　milling　process,　sintered　at　1200　degrees　C　for　3　h.　The　structural,　morphological,　vibrational,　and　microwave　dielectric　properties　of　synthesized　samples　were　analyzed　by　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　Fourier　transform　infrared　spectroscopy　(FT-IR),　and　impedance　analysis.　All　the　samples　have　an　orthorhombic　phase　structure　with　a　space　group　of　Pbnm　formation,　and　the　crystalline　size　and　strain　changes　with　respect　to　Sn4+　doping　were　observed　in　the　XRD　analysis.　From　a　morphological　point　of　view,　on　increasing　the　content　＂x＂,　the　grain　size　reduces　from　3.29　to　1.37　mu　m.　The　existence　of　vibrations　and　the　bridging　stretching　mode　of　Ti-O-Ti　and　Ti-　O-Sn　both　are　associated　with　the　broadband　in　the　region　below　800　cm-1　verified　by　FT-IR.　The　variation　in　electrons　hopping　off　the　host　compound　with　respect　to　Sn4+　ions　was　analyzed　in　AC　conductivity.　The　changes　of　dielectric　properties　such　as　complex　permittivity,　modulus　spectroscopy,　and　dielectric　loss　at　room　temperature　with　a　different　frequency　range　of　1.00-2.00　GHz　are　discussed.
