Thermoplastic 0–3 Ceramic–Polymer Composites With Adjustable Magnetic and Dielectric Characteristics for Radio Frequency Applications
Source abstract
Abstract
Magnetic and electrical properties of thermoplastic ceramic‐polymer 0–3 composites with Z ‐type hexaferrite, and MnZn ferrite inclusions were investigated. The complex permeability and permittivity were measured up to 1 GHz where maximum values of ɛ′ r =30.47 and μ′ r =4.32 and ɛ′ r =10.95 and μ′ r =1.80 were obtained for MnZn‐ER182 and Co 2 Z‐ER182 composites with ∼44.7 vol% and 43.0 vol% filler loadings, respectively. MnZn and Co 2 Z composites exhibit miniaturization factors as low as 0.09 and 0.23, together with reduced magnetic losses and frequency dispersion. The results indicate that the composites offer novel possibilities for wider feasible frequency bandwidth and adjustable impedance matching and magnetic and dielectric properties.
