  • A new kind of low loss ZrTi2O6 filled polytetrafluoroethylene (PTFE) microwave composite substrates were fabricated through the hot-pressing process. The microwave dielectric properties of the composites were measured using dielectric resonator method (18-12 GHz). The relative permittivity (εr) and loss tangent (tanδ) of the composites increase with an increase of the volume fraction of ZrTi2O6 ceramic (0-46%). The experimental dielectric constants of the composites match well with the theoretically predicted values using Lichtenecker model. As the volume fraction of ZrTi2O6 ceramic increases, the thermal expansion coefficient and the temperature coefficient of dielectric constant decrease. The ZrTi2O6/PTFE composites exhibit a dielectric constant of 7.42 with a loss tangent of 0.0022 (10 GHz) at an optimum filler volume fraction of 46% ZrTi2O6.
