Abstract Scope |
The additive manufacturing technology of wireless power transfer (WPT) antenna has been explored to apply the mobility feature of 3D printed devices. In the case of an antenna, the material's electrical properties have a significant impact on the antenna's performance, particularly in this study's wireless energy transmission efficiency. This work challenged a new technique to overcome the poor laser absorption ratio and high thermal conductivity of copper material by using an impulse laser instead of a normal CW laser to construct an additively manufactured pure copper antenna with high electrical attributes. Using a 20-Watt femtosecond impulse laser, this paper demonstrated a 1mm depth pure copper spiral antenna. |
