A radio wave absorber using an Indium Tin Oxide (ITO) resistive-film, a metal plate as a reflection plate and two layers of dielectric plate is proposed. We herein examine the wide-angle absorption characteristics of the absorber under TE and TM polarization waves, theoretically and experimentally. In this structure, two layers of the dielectric plate are arranged in front of the resistive-film for the absorption film under the condition that the permittivity and thickness are chosen accurately. As a result, realization of the absorber for TE and TM polarization waves is confirmed theoretically. Moreover, the absorption of 20dB or more can be obtained based on the designed values of the proposed absorber under the incident angle ranging from 0 to 47.5 degrees for TE and TM polarization waves.
