Abstract
A multi-frequency helix antenna with a helical column having its diameter, material, pitch of circles as well as the total length thereof preset, the top end of the helix antenna has a radially extending section bent inwardly along the central axis of the helical column itself, a predetermined length is bent integrally from the end of the radially extending section orthogonally to extend inwardly along the central axis of the helical column of said helix antenna itself, the antenna is endued with an alternative waving frequency value and the value of the capacity and inductance of the antenna match with each other to give the antenna an equivalent resistance to thereby form a complete harmonic oscillation.
