发明名称 RADIO WAVE ABSORBING BODY
摘要 PURPOSE:To provide a radio wave absorbing body which displays a very excellent radio wave absorbing capacity in a wide band of 30-1000MHz and can be optionally set in frequency band and absorbing characteristics even if it is formed 10mm or below in thickness. CONSTITUTION:Ferrite thin plates of different materials are laminated to constitute a radio wave absorbent, where a range of impedance required to set a radio wave absorbent in frequency band and its absorbing characteristics larger than -20dB is determined, and ferrite which is in the range of impedance concerned is selected or rubber ferrite or plastic ferrite is adequately selected in content ratio. By this setup, a radio wave absorbent having a radio wave absorbing characteristic in a required wide frequency band can be obtained.
