| Abstract: | Dielectric characterization of MgTiO3, CaTiO3 and MgTiO3(x)–CaTiO3(1-x) composite thick films with different concentrations (x = 0.95, 0.50, and 0.20) in the microwave frequency range at room temperature is presented. The films were fabricated by screen-printed method with thickness between 105 and 165 μm. Dielectric constant values between 4.2 and 17.5 and loss tangents between 0.0064 and 0.0098 were measured for frequencies in the range from 3.22 to 3.89 GHz using the coplanar waveguide (CPW) resonators technique. A relationship between the concentration ratio of MTO-CTO in the films and the dielectric constant is also presented. |
