Popis: Perfect absorbing metamaterial based on model of metallic dendritic cell is fabricated. A S-wave band microstrip antenna with perfect absorbing metamaterial substrate is proposed. The results show that compared to the conventional microstrip antenna, the performance of the novel microstrip antenna with perfect absorbing metamaterial substrate has improved remarkably. The direction of the antenna is enhanced, the gain is improved by 1.8dB and its efficiency is increased by 51%. It is proved that the performance of the microstrip antenna is improved by using perfect absorbing metamaterial as its substrate.
