In 3D printing technology, not only synthetic resin material but also conductive metal material in which electricity is energized can be formed by injection.

The method of manufacturing an antenna radiator using 3D printing according to another embodiment of the present invention is a process of forming a pattern portion of an antenna into a conductive metal material by using a 3D printing technique capable of forming a metal into a desired shape, And the metal pattern portion 210 is directly formed of a conductive metal.

In addition, since the 3D printer can form the base part 220 by forming the metal pattern part 210 by spraying the conductive metal with one nozzle and spraying the synthetic resin with the other nozzle by installing two nozzles, The metal pattern portion 210 and the base portion 220 can be formed.

That is, the antenna radiator 200 is provided with a metal pattern portion 210, which is a conductive metal layer, on which a circuit pattern for transmitting and receiving a signal of a specific frequency band is formed, and a base portion 220 that supports the metal pattern portion 210 . In other words, the antenna radiator 200 is manufactured by simultaneously forming the metal pattern portion 210 of the conductive metal material and the base portion 220 of the synthetic resin material by using 3D printing.

The 3D printer for manufacturing the antenna radiator 200 includes a nozzle through which a metal is injected to form the metal pattern part 210 and a nozzle through which a synthetic resin material is injected to form the base part 220, Is installed.

That is, the metal pattern portion 210 is formed through the nozzle through which the conductive metal is injected, and the base portion 220 is formed through the nozzle through which the synthetic resin material is injected, The base portion 220 is manufactured in a shape that is physically mutually fixed. The method of manufacturing the antenna radiator 200 by 3D printing using the 3D printer having the two nozzles described above includes an antenna radiator forming step of performing 3D printing on the metal pattern part 210 and the base part 220, (S20), and a drawing-out step (S21) for drawing out after completion of manufacturing.

The antenna radiator forming step S100 is a step of forming the antenna radiator 200 provided with the patterned metal pattern part 210 and the base part 220 supporting the metal pattern part 210 through a plurality of nozzles provided in the 3D printer And the antenna radiator 200 is formed by performing 3D printing so as to be mutually fixed.

Accordingly, the antenna radiator 200 can be formed into a plate shape in a plurality of quantities in longitudinal and transverse directions at the time of molding by the 3D printing, thereby increasing the number of pieces to be molded at one time, thereby improving the productivity. Further, if the antenna radiator 200 is provided in the form of a plurality of plates, the plurality of antenna radiators 200 can be simultaneously transferred and inspected after being taken out, thereby improving the productivity.

The drawing step S21 is a step of drawing the 3D-printed antenna radiator 200 in the antenna radiator forming step S20.

When the metal pattern portion 210 and the base portion 220 are completely formed by the operation of the 3D printer and the metal pattern fixing protrusion 212 is inserted and fixed in the base fixing groove 222, ). ≪ / RTI >

And a metal pattern fixing protrusion which is inserted into and fixed to the base portion at one side of the metal pattern portion that is in contact with the base portion in the step of forming the antenna radiator, And a base fixing groove into which the pattern fixing protrusions are inserted to be fixed to the metal pattern portion and the base portion,
Method of manufacturing an antenna radiator using 3D printing.
12. The method of claim 11,
Wherein the metal pattern fixing protrusions are formed with inclined metal inclined portions which are inclined so that the cross-sectional area of the metal pattern fixing protrusions is reduced in the direction of the protruded metal pattern portion toward the metal pattern portion, and a base inclination portion inclined to the inclined portion of the metal projection inclination portion Wherein the metal projection inclination portion and the base inclination portion are supported and fixed in accordance with an inclination,
