A matching circuit includes an inductance element formed of a chip inductor connected in series with an antenna body, a first capacitance element formed of a trimmer capacitor, and a second capacitance element formed of a chip capacitor, which capacitance elements are connected between respective ends of the inductance element and a ground terminal, and thus in parallel to the antenna body. One end of the inductance element is connected to the power supply terminal of the antenna body, and the other end is connected to a power source for applying a voltage to the antenna body. The first capacitance element is connected between a ground and the connection point of the power supply terminal of the antenna body and the inductance element. The second capacitance element is connected between a ground and the connection point of the inductance element and the power source.

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.
