Definitions

  • the visible light transmittance of the FSS loading member according to the present embodiment can be increased as described above because a transparent conductive film such as Ag or ITO is used for the conductive portion constituting the FSS.
  • the FSS loading member according to the present embodiment is provided with a coating layer such as a black ceramic layer as the first layer or the nth layer on the second layer or the n-1 layer, it becomes a coating layer.
  • the coating layer such as the black ceramic layer is a layer that shields visible light and is also called a shielding layer.
  • the upper limit of the frequency F is not particularly limited, but may be, for example, 90 GHz or less, or 80 GHz or less.
  • the attenuation for radio waves having a frequency F of 10 GHz or higher tends to be large, and by loading the FSS for radio waves having a frequency F of 10 GHz or higher, the radio wave transparency is improved. It is effective.
