Method and device for manufacturing antenna pattern frame

Abstract

A method of manufacturing an antenna pattern frame, includes arranging antenna radiators in an elongated radiator sheet in the form of cells, the antenna radiators including antenna pattern portions receiving an external signal, and while moving the radiator sheet, forming connection terminal portions of the antenna radiators by a successive bending process and injecting-molding radiator frames such that the antenna pattern portions are formed on one set of respective sides of the radiator frames and the connection terminal portions are formed on the other set of respective opposite sides of the radiator frames.

What is claimed is: 
     
         1 . A method of manufacturing an antenna pattern frame, the method comprising:
 arranging antenna radiators in an elongated radiator sheet in the form of cells, the antenna radiators including antenna pattern portions receiving an external signal; and   while moving the radiator sheet, successively forming respective connection terminal portions of the antenna radiators by using a bending process, and injecting-molding radiator frames such that the antenna pattern portions are placed on one set of respective sides of the radiator frames and the connection terminal portions are placed on the other set of respective opposite sides of the radiator frames.   
     
     
         2 . The method of  claim 1 , wherein each of the antenna pattern portions is connected with the radiator sheet by a support pin, and is separated from the radiator sheet after the injection-molding. 
     
     
         3 . The method of  claim 2 , wherein a notch, a relief recess, or the notch and the relief recess are formed in a connection portion between the antenna pattern portion and the support pin, and serve to facilitate the separation of the antenna pattern portion from the support pin. 
     
     
         4 . The method of  claim 1 , wherein the bending process and the injection-molding are respectively performed by a bending mold and an injection mold by stages. 
     
     
         5 . The method of  claim 1 , wherein the radiator sheet is moved continuously by a supply reel and a pick-up reel. 
     
     
         6 . A method of manufacturing an antenna pattern frame, the method comprising:
 forming radiator-sheet units by grouping antenna radiators arranged in the form of cells and including respective antenna pattern portions receiving an external signal;   forming connection terminal portions of the antenna radiators of each radiator-sheet unit by using a bending process simultaneously or by stages; and   injection-molding radiator frames such that the antenna pattern portions of the radiator-sheet unit are placed on one set of respective sides of the radiator frames and the connection terminal portions are placed on the other set of respective opposite sides of the radiator frames.   
     
     
         7 . The method of  claim 6 , wherein each of the antenna pattern portions is connected with the radiator sheet by a support pin, and is separated from the radiator sheet after the injection-molding. 
     
     
         8 . The method of  claim 7 , wherein a notch, a relief recess, or the notch and the relief recess are formed in a connection portion between the antenna pattern portion and the support pin, and serve to facilitate the separation of the antenna pattern portion from the support pin.
