Chip antenna
First Claim
1. A chip antenna comprising:
- a base member made from a material having a relative magnetic permeability μ
which satisfies the condition of 7≦
μ
<
35;
at least one conductor formed at least one of on a surface of the base member and inside said base member; and
at least one feeding terminal for applying a voltage to said conductor disposed on a surface of said base member.

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.
