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.
Claims9
An antenna pattern manufacturing method comprising:
- laminating a carrier sheet on a first surface of a metal sheet;
- punching a second surface of the metal sheet facing the first surface to form a first half groove recessed in an inward direction of the metal sheet from the second surface of the metal sheet;
- laminating a coverlay sheet on the second surface of the metal sheet in which the first half groove is formed;
- removing the carrier sheet formed on the first surface of the metal sheet;
- exposing the first surface of the metal sheet with the carrier sheet removed;
- and
- half-etching the first surface of the metal sheet to form a second half groove recessed in an inward direction of the metal sheet from the first surface of the metal sheet.
