Miniaturized and reconfigurable Notch antenna based on BST thin film

Abstract : In recent years, reconfigurable antennas have received significant attention for their application in modern telecommunication systems. The requirements for increased functionality within a confined volume place a greater burden on today's transmitting and receiving systems with frequency agile capabilities. Many solutions have been proposed in the literature, including the use of ferroelectric materials, such as KTN and BST. In this work, the design, realization and characterization of a small and tunable antennas loaded by a Ba0,80Sr0,20TiO3 ferroelectric thin film, obtained from chemical solution deposition, are studied. The integration of a capacitive structure in a Notch antenna can miniaturize and change the resonance frequency of this antenna by applying a DC electric field. Monolithic integration is used for realizing the BST loaded antenna prototype. Characterization shows a frequency agility of 14.5% under DC electric field of 375kV/cm, which is one of the best performances reported in the literature with this technology.
