<P>PROBLEM TO BE SOLVED: To provide a low-priced planar antenna having a sharp directivity and excellent radio wave characteristics and a method of manufacturing the same. <P>SOLUTION: A method of manufacturing a planar antenna includes the steps of: forming patterns 3, 4 comprised of a plurality of projections on a surface of a substrate 1; tightly adhering masks 23, 25 having holes 22, 24 corresponding to the patterns 3, 4 on the surface of the substrate 1 where the patterns 3, 4 are formed; performing processing for reducing a tight adhesion strength for a conductor film on the surface of the substrate exposed from the holes 22, 24 by performing strong ultraviolet ray radiation 26 while tightly adhering the substrate 1 with the masks 23, 25; performing processing for improving the tight adhesion strength for the conductor film on the surface of the substrate other than a portion 27 where the tight adhesion strength is reduced by performing appropriate ultraviolet ray radiation 28 after the masks 23, 25 are removed; forming a conductor film 2 with a predetermined film thickness on the surface of the substrate; and removing conductor films 29, 30 formed on the portion 27 where the tight adhesion strength for the conductor film on the substrate 1 is reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
