Abstract

In this study, an epoxy-modified urethane rubber mixed with carbon particles is chosen as a material of a millimeter wave absorber. The single-layer absorber is designed and produced for 60GHz band on the basis of no reflection curve and the equation of its permittivity. The absorption characteristics of the specimens were measure at the frequency of 50 to 110GHz by power reflection method. As a result, the good millimeter wave absorber with the absorption of 20dB or more was obtained at both 60GHz and 100GHz bands.
