Abstract

An antenna having a helically formed conductor positioned closely adjacent and in parallel relation with a conductor image means such as a conductive surface or the ground or another helix to provide an "image" of the helical conductor when the same is energized and thereby effectively cancel the vertically or axially polarized wave component and intensify the horizontally or transversely polarized wave component of the energized helical conductor.
