Abstract

The invention discloses a processing method and device for a shape-controllable three-dimensional (3D) spiral micro-antenna. The device comprises a micro wire generation chamber, a coaxial nozzle anda supported liquid container, wherein the micro wire generation chamber is sequentially divided into an upper-layer cavity, a middle-layer cavity and a lower-layer cavity from top to bottom; the upper-layer cavity of the micro wire generation chamber is a microflow chamber; the middle-layer cavity of the micro wire generation chamber is an ultraviolet light curing chamber; the lower-layer cavity of the micro wire generation chamber is a rotary light source chamber; a rotary light source is arranged in the rotary light source chamber and rotates around an axis of the coaxial nozzle; the coaxialnozzle is arranged in the microflow chamber; and the supported liquid container is arranged under an outlet end of the rotary light source chamber. Through regulating the extruding speed of liquid inthe coaxial nozzle, the rotary speed of the rotary light source and the laser power emitted by the rotary light source, the shape controllability of the prepared 3D spiral micro-antenna can be realized.
