Abstract:
PURPOSE: To obtain delay time which is small in size but large by providing a zigzag strip line on the surface of a dielectric film and a ground electrode in an area, covering the rear surface side of a strip line on the rear surface and folding the film in the manner of a folding screen CONSTITUTION: A delay line element 12 forms a zigzag and right/left symmetrical strip line 14 on one of the main surfaces of the rectangular dielectric film 13 and a ground electrode 15 in the area covering the rear surface side of at least the line 14 on the rear surface. This is folded in a manner of a folding screen by the part of alternate long and short dash lines L1 to L3 , namely the unit of the line 14. Teflon (R), polyimide, etc., can be used as the material for the film 13. It is prefered to thermo-compress a copper film onto the film 13 as a means of forming the line 14 and the electrode 15.
