Abstract
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.
