MULTI-BAND CERAMIC CHIP ANTENNA

摘要

PURPOSE: A ceramic chip antenna includes a plurality of helical conductors operated in a different frequency band in the inside of a ceramic chip, so that it is possible to be used in a plurality of frequency bands. CONSTITUTION: A multiple band ceramic chip antenna includes a body formed as a cube shape as of a ceramic dielectric substance, and a plurality of helical conductors independently formed in the inside of the body. The plurality of helical conductors includes at least one main helical conductor of a helical shape, and a plurality of sub-helical conductors helically formed in the inside of each main helical conductor. A spiral rotation shaft of each helical conductor is in parallel arranged to a bottom surface and a lateral surface. Since a length of each helical conductor is differently formed so that usable frequency bands are to be different from each other. Accordingly, a plurality of frequency bands can be used, the chip antenna can be included in a cellular phone and a relative wide band width.
