하이브리드 적층 인덕티브 안테나 제조기법 연구

초록

When conductive material inking and direct deposition of conductive materials are performed during the 3Dprinting of nonconductive polymer materials, multifunctional products such as electronic circuits and electroniccomponents can be directly manufactured. In a previous study, wireless power transmission technology wasdeveloped through the fabrication of an inductive coil antenna by concurrently stacking pure copper wires withspiral shapes on an embedded layer plane. This study aims to enhance the power transmission characteristics of3D-printed inductive antennas by utilizing the shielding and high-permeability properties of ferrite. The studyproposes a hybrid additive manufacturing method for embedding sheet-type ferrite on a 3D printing layer andinserting and stacking a ferrite core after creating a cavity in the center. Comparative evaluation experimentsdemonstrated improvements in wireless power transmission performance.
