Abstract :
We proposed EM-wave absorber with periodic patch antennas. It has two feed points on a square patch. We simulated electromagnetic field of patch antennas having infinite periodic structures by using FDTD method and designed at 2.4GHz band. Then, we manufactured and measured the EM-wave absorber for 2.45GHz. As a result, both H- and V-polarized waves could be absorbed at 2.4GHz.
