Moldable Polymer/Ferrite Composite and Application to an Integrated CPW Tunable Phase Shifter

A moldable polymer/ferrite composite (MPFC), easily moldable into arbitrary volumetric shapes is presented. The composite material is produced at room temperature and does not require any postprocessing treatment. The utility of the MPFC is demonstrated in a meandrous coplanar waveguide line phase shifter tuned by an applied magnetic dc field. Due to its low cost and high flexibility, the proposed MPFC may find applications in various tunable and non-reciprocal microwave components.
