US 2003/0222822 A1 · Ceramic chip antenna

Abstract

A ceramic chip antenna for use in ultra-high frequency communications. The ceramic chip antenna according to the present invention comprises a main body, first and second helical conductors, and a single power supply section for supplying power to the first and second helical conductors. The main body is produced by laminating a plurality of ceramic sheets made of a dielectric material. The first and second helical conductors are formed inside the main body by a screen-printing method. The first and second helical conductors have the same axis of helical rotation, as view from the power supply section.
