摘要：

The theory aspects of the design of optimal construction of microwave ferroelectic phase-shifter are discussed. The 30 GHz phase-shifter based on grounded coplanar waveguide with layered structure was under investigation. As a result expressions to determine the optimal construction of CPW ferroelectric phase-shifter and the suitable composition of ferroelectric film are derived. Continuos 0-360 degree phase shift and maximum insertion losses of 8 dB have been experimentally demonstrated by Ka-band ferroelectric phase-shifter. Further optimization in point of suitable ferroelectric film composition and phase-shifter sizes makes it possible to achieve figure of merit similar to 80 deg/dB.
