ANTENNA USING MAGNETIC MATERIAL AND APPARATUS COMPRISING THE SAME

摘要

An antenna and a device including the same are provided to perform multiband and broadband property by using magnetic material magnetized to particular direction. An antenna comprises an antenna radiator(210) and magnetic material(110). The antenna radiator has a shape including one or more cyclic structure, is made of conductive material, and is vertically arranged on a ground surface(300). The magnetic material is arranged in an inner side of the cyclic structure of the antenna radiator. The magnetic material and the antenna radiator are separated each other. The antenna radiator is a helical or loop antenna. A magnetizing amount of the magnetic material is changed according to a bias voltage supplied in the antenna radiator.
