Abstract :
A key component of a phased array antenna is a phase shifter. The current status of ferroelectric (and paraelectric) thin film processing enables one to expect that a tuned microwave device based on this film can be competitive with microwave ferrite and PIN diode phase shifters. An epitaxial film of BST-Ba0.5Sr0.5TiO3-composition was deposited by laser ablation on an MgO substrate. With this film, a coplanar waveguide phase shifter was realized and studied. Detailed simulation of different constructions allowed the optimal design of phase shifter for MMIC to be found
