This paper describes the design, modeling, and realization of a tunable left handed (LH) phase shifter using thin film Ba<sub>0.25</sub>Sr<sub>0.75</sub>TiO<sub>3</sub> (BST) ferroelectric varactors. The unique nature of LH transmission line (TL) metamaterials enables reduced size, compared to conventional loaded line phase shifters realized as right handed(More)
