Abstract

In this paper characterization of ferroelectric ceramic-polymer composites at microwave frequencies is presented. Tested materials are composed of barium strontium titanate (BST) and polyvinylidene fluoride (PVDF). The influence of three different shapes of ceramic particles is investigated. Measurement setup for determining the permittivity and tunability is described. Results show that the rod-like BST/PVDF composite has the best dielectric constant and tunability at 10 GHz with a value of 13 and 9% at 6 V/μm, respectively.
