Abstract: The present disclosure presents an antenna pattern manufacturing method which, by forming a through hole in a metal sheet via a punching and an etching process, enables the precise formation of the line spacing of an antenna pattern. The presented antenna pattern manufacturing method comprises forming a first half groove in one surface of a metal sheet via a punching process and a second half groove in the other surface of the metal sheet via an etching process, wherein the first half groove and the second half groove at least partially overlap to form a through hole penetrating through the metal sheet.

Abstract: The present disclosure relates to an antenna pattern in a loop shape, which is mounted in a mobile terminal, etc., and used for wireless power transmission/reception or communication, and to a manufacturing method therefor, which enables the precise formation of the line spacing (or line width) of an antenna pattern by preparing a laminated substrate having metal layers formed on both surfaces of a base substrate and forming half grooves in the first and second surfaces of the laminated substrate, respectively, through double half-etching, wherein the half grooves at least partially overlap to construct a through hole forming a line spacing (or line width) of an antenna pattern.
