A Low-Loss Time-Delay Phase Shifter Controlled by Piezoelectric Transducer to Perturb Microstrip Line

Tae-Yeoul Yun and Kai Chang Fellow, IEEE

Page 96.

Abstract:

This paper presents a new time-delay phase shifter using a piezoelectric transducer (PET) on microstrip line with computational and experimental results. Dielectric perturbation changes the line capacitance and propagation constant of the microstrip line. The phase of the microstrip line is varied, but insertion loss is not much affected. A maximum phase shift of 460° The proposed phase shifter should have many applications in antenna beam steering and in other microwave and millimeter-wave circuits.
