Abstract

An S-band left-handed tunable phase shifter based on Barium-Strontium-Titanate (BST) thin film is developed. The application of left-handed transmission line considerably reduces the size of the phase shifter. The phase shift reaches about 124 degree while the permittivity of the BST film ranges from 225 to 450. The Figure of Merits (FoM) of the phase shifter reaches up to 42.48 °/dB as the insertion loss keeps about -3dB from 2.1GHz to 2.6GHz. Moreover, the coplanar strip structure of the phase shifter makes it suitable for balanced components.
