摘要： A miniature chip antenna suitable for use in low-frequency-band mobile communications is disclosed. The chip antenna has a rectangular-prism-shaped base member provided with a mounting surface. Disposed within the base member is a conductor spirally wound along the height of the base member. The base member is formed from e.g., ferrite comprising Ni--Zn having a relative magnetic permeability of 7. The conductor is made from a metal comprising, e.g., Cu, Ni, Ag, Pd, Pt, or Au, and is formed by printing, depositing, laminating or plating. The base member and the conductor are then integrally sintered. A conductor having a rectangular cross section and spirally wound along the height of the base member is thus formed within the base member.

The chip antenna includes a rectangular-prism-shaped base member having a mounting surface. A conductor, e.g. silver, is spirally wound inside the base member. A feeding terminal is formed over surfaces of the base member so as to feed power to the conductor. One end of the conductor is extended to a surface of the base member to form a feeding section, which is connected to the feeding terminal. The other end of the conductor serves as a free end within the base member. The base member is produced by laminating mixture layers made from a mixture of glass essentially consisting of borosilicate having a softening point of approximately 700.degree. C. and ceramic (relative dielectric constant: 60) essentially consisting of barium oxide, neodymium oxide and titanium oxide having a sintering temperature of approximately 1300.degree. C.

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.
