Abstract
An antenna module () has an antenna () that is formed on a ferrite substrate (), and the ferrite substrate is positioned within a small direct current (DC) magnetic field. The magnetic loss tangent of the ferrite is controlled by application of the small DC magnetic field, thereby improving antenna radiation efficiency and increasing the bandwidth of the antenna.
