The present invention relates to a helical antenna formed in 2D format and to a production method for the same, and more specifically relates to a helical antenna for various forms of mobile communication terminal; the helical antenna being a helical antenna formed in 2D format, wherein a plurality of semicircular linear antenna patterns are formed in the same direction on the upper surface of a mobile communication terminal device casing (110) having a dielectric constant, while, on the lower surface of the mobile communication terminal device casing (110), semicircular linear antenna patterns are formed in a direction symmetrical to that of the linear antenna patterns formed on the upper surface, the terminal parts of the linear antenna patterns formed on the upper surface and the lower surface are electrically connected through a via hole formed passing through the mobile communication terminal device casing (110), and the linear antenna patterns are formed in a two-dimensional flat type arrangement by means of etching, printing or spot processing. |
