Magnetic-Dielectric Property of FeAlSi-CCTO-Epoxy Composite for Antennas Miniaturization and Embedded Inductor-Capacitor Application
This paper reports a FeAlSi (sendust)/CaCu3Ti4O12 (CCTO)/Epoxy three-phase composite prepared through a simple procedure. The magnetic-dielectric properties of the composites were analyzed using impedance analyzer (Agilent 4991) in a frequency range from 106 to 109 Hz. The results show the weak coupling effect between the FeAlSi and CCTO fillers in the three-phase composite. The real permeability (μ′) of the composite slightly increases from 1.4 to 1.6 with the CCTO content increasing from 3vol% to 18vol% at 108 Hz. The magnetic loss tangent remains at a relatively low level. The real dielectric constant (εr′) of the composite rises from 14 to 24.5 with the low loss tangent about 0.05 when the volume fraction of CCTO (fCCTO) increases from 3vol% to 18vol% at 108 Hz and room temperature. The applications in antenna miniaturization and embedded capacitors and inductors were discussed in view of several aspects.
