In this study, we investigated the effect of particle size of Mn-Zn ferrite which is used as a material of electromagnetic wave absorber on electromagnetic wave properties. With increasing the particle size, the matching frequency is shifted toward lower frequency and the absorption ability of electromagnetic wave is decreased. We suggest that a sheet-type ferrite absorber composed of Mn-Zn ferrite with large particle is useful to compare with it composed of small particle size for mobile phone.
