Abstract
A ceramic chip antenna, which has a small size and a broad bandwidth, is provided. The ceramic chip antenna consists of a ceramic body with cuboid shape, a conductor wound helically inside the ceramic body, and signal-feed terminal formed on a surface of the ceramic body. The ceramic chip antenna with a helical conductor patterns formed in a symmetrical dipole shape is provided, which has a high gain value and excellent radiation characteristics. Also, it can be built-in inside a mobile terminal due to its small size. The ceramic chip antenna according to the present invention can have a broad bandwidth that satisfies the variable frequency of the present mobile communication system.
