FERRITE UNIT FOR ABSORBING RADIO WAVE AND RADIO WAVE ABSORBING PANEL

摘要

PROBLEM TO BE SOLVED: To reduce the weight of an electronic wave absorbing panel for both VHF and UHF by arranging a plurality of ferrite rods having specified width and thickness continuously in one direction at an interval of specified gap rate in the vertical direction and then integrating them with a foamable resin material. SOLUTION: A plurality of ferrite rods 3 are arranged continuously in one direction at an interval in the vertical direction and integrated with a foamed resin material 4 to constitute a ferrite unit 5 absorbing radio wave. The ferrite rod 3 suitably has a width of 5-12 mm and a thickness of 15-20 mm. In the ferrite unit 5 absorbing radio wave, the ferrite rods 3 are arranged continuously in the direction of the magnetic field component of incoming radio wave and arranged at an interval in the direction of the electric field component thereof. The gate rate is set at 70-86%. According to the structure, a radio wave absorbing panel dealing with radio wave of different incident angles over a wide range can be obtained.
