The microwave dielectric properties and structural variation of Sm doped Ba4La9.33Ti18O54 have been investigated. Ba4(La(1-y)Smy)9.33Ti18O54, y = 0.0.0.7 ceramics were prepared by conventional solid state route. The electric permittivity and loss tangent were measured using a network analyzer in the frequency range of 0.3.3.0 GHz at room temperature. The loss tangent decreases significantly upon increasing Sm contents, along with a slight reduction in electric permittivity. A relatively good combination of dielectric properties was obtained for y = 0.5 (ε = 83.3 and tanδ = 0.021 at 3.0 GHz). X-ray diffraction and scanning electron microscopy were applied to investigate the microstructure and correlate it with microwave dielectric properties.
