    摘要： 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.

The helical antenna includes a conductor which is formed from copper or a copper alloy inside a base in the shape of a rectangular parallelopiped formed from a dielectric material having barium oxide, aluminum oxide and silica as main constituents and which is wound in a helical shape along the length of the base. In such a case, the resonance frequency f0 of the helical antenna and the inductance components L of the conductor satisfy the relationship: ln (L)=A0+A1.times.ln (f0), where ln is a natural logarithm, and A0 and A1 are constants. One end of the conductor is extended onto the surface of the base and forms a power feeding terminal connected to a power feeding terminal formed on the surface of the base for applying a voltage to the conductor, and the other end thereof forms a free end inside the base.
