BROADBAND ELECTROMAGNETIC WAVE ABSORBER

摘要

An electromagnetic wave absorber is provided. The electromagnetic wave absorber includes multiple unit cells arranged with a matrix shape. The unit cell includes a dielectric substrate. Conductive closed loops are arranged on the dielectric substrate. The conductive closed loops include at least two types of group consisting of a center closed loop of which center is located in the center of the unit cell, vertex closed loops located in the center of the four vertices of the unit cell, and a side closed loop located in the center of the four sides of the unit cell. A conductive plate is arranged on the lower surface of the dielectric substrate.
