Disclosed is a helical antenna manufacturing apparatus and method. A controller controls a core driver and a roller driver to rotate a core and a roller according to an rpm which is pre-set according to diameters of the core and the roller, and controls the core driver to move the core in a longitudinal direction according to the moving speed which is set according to working frequency bands of the antenna. When the core and the roller are contacted, they are rotated in opposite directions, and as the roller is rotated, a paste in a paste box moves together with a surface of the core and is printed on the surface of the core. As the core is rotated and moved in the longitudinal direction, a helical line is formed on the core. Pitches of the helical line formed on the core is changed according to the moving speed of the core in the longitudinal direction, and the working frequency bands of the antenna are changed according to the pitches of the helical line. Also, a helical line unit including a plurality of helical lines having different pitches printed on the surface of the core can be formed by controlling the core driver to move the core in the longitudinal direction according to the moving speeds which are set for the respective steps according to the working frequency bands of the antenna.

Helical antenna manufacturing apparatus and method thereof

A ceramic chip antenna is provided which exhibits a small size and is capable of utilizing a plurality of bands. The ceramic chip antenna comprises a dielectric chip base, a plurality of main conductors which is spirally wound within said dielectric chip base, and a plurality of sub conductors which is spirally wound within each of said main conductors. The sub conductors are respectively separated. One ends of said main conductors are led to an outside surface of said dielectric base to form feeding terminal for applying a signal to said main conductors and one ends of said sub conductors are led to an outside surface of said dielectric base to form feeding terminal for applying a signal to said sub conductors.
