Ceramic chip antenna
First Claim
1. A ceramic chip antenna comprising:
- a dielectric chip base;
at least one conductor which is spirally wound within said dielectric chip base; and
at least one sub conductor which is spirally wound within said conductor such that said conductor and said sub conductor are respectively separated, andwherein one end of said conductor is led to an outside surface of said dielectric base to form a feeding terminal for applying a signal to said conductor, and one end of said sub conductor is led to an outside surface of said dielectric base to form a feeding terminal for applying a signal to said sub conductor.

Abstract
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.

8. A method of manufacturing a ceramic chip antenna comprising the steps of:
-
providing a plurality of dielectric ceramic sheets; depositing conductive strip patterns on a first set of dielectric ceramic sheets, wherein the conductive strip patterns define horizontal portions of a conductor; depositing conductive strip patterns on a second set of dielectric ceramic sheets, wherein the conductive strip patterns define horizontal portions of a sub conductor; forming vertical holes through at least some of the dielectric ceramic sheets; and assembling the dielectric ceramic sheets into a ceramic chip antenna, wherein said assembling step comprises; filling the vertical holes with electrically conductive paste; stacking the dielectric ceramic sheets on top of each other such that the conductive strip patterns and vertical holes of the dielectric ceramic sheets define a sub conductor that is spirally wound within a conductor, wherein the conductor and sub conductor are separated, and wherein one end of the conductor and one end of said sub conductor are led to an outside surface of the ceramic chip antenna to form feeding terminals for applying signals to the conductor and sub conductor; and forming the ceramic chip antenna from the dielectric ceramic sheets. - View Dependent Claims (9, 10, 11, 12, 13, 14)
