Abstract

Ferroelectric (FE) thin film varactor technology can be used for antenna miniaturization and reconfiguration. We present more particularly a quarter wavelength notch antenna with a Barium Strontium Titanate (Ba(1-x)SrxTiO3, BST) thin film in MIM geometry. Integration of the BST varactor yields a size reduction of approximately 56% with respect to the initial antenna size (0.064  0 without BST layer) and the miniaturized antenna is tunable from 0.94 GHz to 1.07 GHz.
