Ferrite pastes for additive manufacturing of microwave devices
摘要
The paper studies ferrite pastes based on lithium-containing ferrite (Li0.4Fe2.4Zn0.2O4). A selection of the binder composition is described herein. Pastes based on the binding terpineol with polyethylene glycol demonstrate the best porosity and application quality. The frequency response of the microstrip transmission line with a ferrite sublayer is studied. As a result, the determined parameters of the ferrite layer are determined to be the dielectric permittivity (ε = 16), loss-angle tangent (tanδ = 0.3) and magnetic permeability (μ = 40).
