Patent ID: 8502741

Claim:
A structure for adjusting an electromagnetic wave (EM wave) penetration response, comprising: a dielectric substrate, provided with an upper surface and a lower surface; and a plurality of structure units, disposed on the upper surface, the lower surface, or the upper surface and the lower surface of the dielectric substrate, wherein the structure units consist of a plurality of meandering metal lines, a plurality of metal patch-shaped structures, a plurality of complementary slits, or a combination thereof, to enable the EM wave penetration response of the structure for adjusting the EM wave penetration response to at least comprise a pass band and a stop band, wherein the stop band is adjacent to the pass band, and a frequency of the stop band is higher than that of the pass band, if a distance between the structure for adjusting the EM wave penetration response and an object with a high dielectric constant is longer than a predetermined distance, the pass band covers a radiation frequency of an antenna; and if the distance between the structure for adjusting the EM wave penetration response and the object with the high dielectric constant is within the predetermined distance, the stop band covers the radiation frequency of the antenna.
