The Research of the Absorption and Angle Characteristics of Honeycomb Hexagon Phase Modulation Membrane

Abstract:

According to the honeycomb hexagonal phase modulation membrane, this paper designed and prepared λ/4 electromagnetic wave absorber. Studies have shown that the honeycomb hexagonal phase modulation membrane structure can realize the absorber width. Experiments have shown that 65% of bandwidth below-10 dB was achieved under following conditions: line length a = 4 cm, line weight b = 6 mm. For line length a = 4 cm, line weight b = 6 mm, the angle characteristics of phase modulation membrane was studied. The study of angle characteristics have shown that, absorption peak moved backward with the angles increasing. This new composite materials can be used for electromagnetic interference protection for WLAN and indoor electromagnetic radiation pollution control.
