Since the arrival of the IoT era, the development of tunable multifunctional devices in the microwave and millimeter wave bands is required. We have proposed liquid crystal loaded phase shifter in microwave band, whose phase shifter operation is based on anisotropy in dielectric permittivity for the applied electric field. In this study, we are developing the ferroelectric thin film loaded phase shifter in which the liquid crystal layer is replaced with the ferroelectric thin film. In this report, for application in the RF band, optimum deposition condition of Ba(Zr,Ti)$O_3$ film in which Zr is substituted for the B site of BaTi$O_3$ were examined from the results of structural analysis, film quality and dielectric properties. As a result, it was confirmed that sintering at a higher temperature promotes growth of crystal grains, and high dielectric permittivity and tunability properties can be obtained. |
