Abstract

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.

Dependent claims

A chip antenna comprising:

a base member made from at least one of a dielectric material and a magnetic material;
at least one conductor formed at least one of on a surface of said base member and inside said base member;
and at least one feeding terminal formed on a surface of said base member for applying voltage to said conductor, said conductor being connected at a first end to said feeding terminal and having a second end, the second end being connected to a portion of said conductor other than the first end of said conductor connected to said feeding terminal, thereby forming a loop in said conductor.
