In order to widen the band-width of ferrite absorber, compositional effect on the complex permeability of Ni-Zn ferrite and the structure of grid absorber were studied. From the experimental results, we could determine the optimum composition of Ni-Zn ferrite and the structure of grid absorber. Also, we manufactured grid absorber and investigated its microwave absorbing characteristics. Calculation shows that the ferrite grid absorber suppresses reflection ≤ -20dB from 30 ㎒ to 700 ㎒ and the conventional ferrite tile absorber suppresses reflection ≤ -20dB in the frequency range of 30 ㎒-400 ㎒. It was found that the microwave absorbing performance of the ferrite grid absorber was superior to the ferrite tile absorber.
