CO2Z TYPE FERRITE FOR HIGH-FREQUENCY APPLICATIONS, A PRODUCTION METHOD FOR THE SAME AND AN ANTENNA USING THE SAME

摘要

The present invention relates to a CO2Z type ferrite for high-frequency applications, to a production method for the same and to an antenna using the same. More specifically, by substituting Mn and Zn in the Co position, both the dielectric constant and the magnetic permeability can be kept higher than predetermined levels, and device miniaturisation can be achieved without bandwidth reduction or tangent loss.
