ABSTRACT:
A chip antenna which provides a high gain and large band width and which makes it possible to achieve a reduction in the size of the chip antenna. The chip antenna has a dielectric base which is formed as a rectangular parallelepiped containing a spirally wound conductor whose winding axis is perpendicular to the longitudinal dimension of the dielectric base and parallel to the mounting surface. The configuration of the winding cross section S, which is perpendicular to the winding axis of the conductor, is a rectangle whose longitudinal vertical dimension is H and whose horizontal dimension is W. One end of the conductor is led out to the surface of the dielectric base to form a feeding end that is connected to a feeding terminal for applying a signal to the conductor, and the other end thereof forms a free end within the dielectric base.
