Structural and Dielectric Properties of Magneto-Dielectrics for Antenna Application
The sintering behavior and high frequency electromagnetic properties of Ba3Co2Fe24O41 ceramics were investigated for the small antenna application. All samples of the Ba3Co2Fe24O41 ceramics were prepared by the conventional mixed oxide method and sintered at 1150℃～1400℃. From the XRD patterns of calcined Ba3Co2Fe24O41 powders, the most suitable condition for calcining was 600℃-1000℃. Ba3Co2Fe24O41 phase was observed in sintered Ba3Co2Fe24O41 ceramics as main phase. Bulk densities increased with sintering temperature and decreased at 1400℃. Permittivity and permeability of the Ba3Co2Fe24O41 ceramics increased or decreased with sintering temperature, respectively. On the other hand, loss tangent of permittivity and permeability showed contrary tendency with permittivity and permeability. The permittivity and loss tangent of permittivity of Ba3Co2Fe24O41 ceramics sintered at 1300℃ were 19.896 and 0.171 at 210 MHz. And the measured value of permeability and loss tangent of the permeability were 14.218 and 0.204, respectively.
