Loop antenna, method for manufacturing loop antenna thereof and methodfor manufacturing RFID card using loop antenna

摘要

loop antenna with a polymer film to form a metal pattern is transferred using a dongjeonju plated and therefore suitable for loop The antenna manufacturing method are disclosed. The loop antenna is the through-hole is prepared in position to be connected to the first metal pattern and the second metal pattern, wherein the first metal pattern and is transferred to the surface of the intermediate film and the second metal pattern is transferred onto the back surface ; An upper cover film for covering the surface and wherein the first metal pattern of the intermediate film; And a lower cover film for covering the back surface and the second metal pattern of the intermediate film. Loop antenna manufacturing method according to the present invention has a small effect in the risk of environmental pollution compared to using a conventional etching process waste water treatment costs are reduced because the need to form a metal pattern in the loop antenna by the electroforming. ;
