A method of forming an antenna pattern is provided to integrate the antenna pattern into an injection molding simply, exhibit an antenna pattern having an elaborate and fine structure, and form the antenna pattern also in three dimension correspondingly to an injection molding having a three-dimensional shape. A method of forming an antenna comprises the steps of: mixing a base polymer(112) with a laser reactive agent comprising a filler(113) and a metal component(114); forming a plastic injection molding comprising a composite polymer using the mixed material(115); activating a surface of the plastic injection molding along a predetermined pattern using the laser beam; plating the activated surface of the plastic injection molding to form an antenna pattern; and coating the antenna pattern and its periphery to protect the pattern. The step of activating the surface of the plastic injection molding comprises the step of forming a metal seed along the predetermined pattern on the surface of the plastic injection molding, and the step of forming the antenna pattern comprises the step of plating the antenna pattern by means of the formed metal seed. The step of coating the antenna pattern and its periphery comprises the process of coating an UV(ultraviolet) coating liquid, and exposing a coated part to UV rays to harden a coating layer. |
