Abstract
A shielding box configured for regulating a transmission distance of a radio frequency (RF) signal of an electronic device is used as a container of the electronic device. The shielding box includes a box body. The box body includes a wave-absorbing layer, a first metal layer, a conductive fabric layer, a second metal layer, and a third metal layer in that order from inside to outside. An RF signal attenuation system and method are also provided.
Claims15
A shielding box comprising:
- a box body comprising a wave-absorbing layer, a first metal layer, a conductive fabric layer, a second metal layer, and a third metal layer from inside to outside in that order.
