Title: Radio wave absorbent
Inventor: ICHIMURA KAZUO
IPC: H01Q17/00
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To effectively attenuate radio wave, at a low cost. SOLUTION: A resonance circuit constituted of a coil 4 formed by winding conductor and a capacitor 5 connected with both ends of the coil 4 is arranged on a surface of magnetic substance 1 like ferrite. When this radio wave absorbent is arranged in the vicinity of a radio wave generating source, permeability of the magnetic substance 1 is remarkably higher than that of peripheral air, so that magnetic flux at the periphery is converged and interlinked with the coil 4. A current whose frequency is approximate to the resonance frequency determined by inductance L of the coil 4 and capacitance C of the capacitor 5 is induced in the coil 4, and heat is generated by causing resistance loss. As a result, the energy of magnetic field of radio wave near the frequency is consumed as heat, and the radio wave is effectively attenuated.
