3-D Printed Dual-Band Microwave Absorber based on Perforated Geometry
In this paper, a three dimensional (3-D) printed dual-band microwave absorber is presented. The proposed geometry is designed on a perforated dielectric substrate to reduce the overall volume as well as weight of the device. Lowcost Polylactic acid (PLA) material is used in 3-D printing technology to realize the perforated structure, on top of which a conductive ink is deposited in annular ring patterns. The proposed structure exhibits two discrete absorption peaks at 6.86 GHz and 11.26 GHz with corresponding absorptivities of 98.42% and 99.92%. In addition, the topology is angularly stable as well as polarization-insensitive. Parametric variations and surface current distributions are also studied to investigate the operating principle of the proposed 3-D printed absorber.
