ABSTRACT:
A method of easily and inexpensively manufacturing an antenna for an RFID tag by forming the antenna using magnets of a pattern corresponding to a shape of the antenna is provided. One example method includes a) placing a substrate above a level of a fluid containing a conductive substance, b) placing a magnet (e.g., an electromagnet including an electrode) formed in a shape of an antenna pattern above a surface of the substrate, and adhering the conductive substance to a bottom of the substrate in the shape of the antenna pattern by a magnetic force, and c) fixing the conductive substance adhered to the bottom of the substrate.
