摘要：
A coplanar waveguide linear resonator technique for the experimental characterization of the dielectric properties of films in the microwave frequency range at room temperature is proposed. The approach is simple to implement as it consists of a film with unknown high dielectric constant deposited over the resonator, printed on standard alumina substrate using conventional photolithography process. The technique is illustrated by the measurement of the dielectric constant and losses of various ceramic screen-printed thick films: BaTiO3 (BTO), CaCu3Ti4O12 (CCTO), and a BTO(x)-CCTO(1-x) composite with different concentrations (x =0.2, 0.5, and 0.8).
