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.

摘要： A downsized chip antenna having a large bandwidth ratio is disclosed. The chip antenna has a rectangular prism-shaped base member providing a mounting surface. A conductor is formed inside the base member in such a manner that it is spirally wound around a winding axis, for example, a winding axis parallel to the mounting surface, i.e., in the longitudinal direction of the base member. One end of the conductor is extended to a surface of the base member to form a feeding section, which is connected to a feeding terminal, disposed over the surfaces of the base member to apply voltage to the conductor. In one embodiment, the other end of the conductor is connected to a midway portion of the conductor within the base member, thereby forming a loop in said conductor.
