Abstract

See full text

In an antenna apparatus, a first current is induced in a first booster conductor by a current flowing through a coil conductor of a power feed antenna, and the first current circulates along a circumference of the first booster conductor. A second current is induced in a second booster conductor by the current flowing through the coil conductor of the power feed antenna, and the second current circulates along a circumference of the second booster conductor. A third current is induced in the first booster conductor by the second current flowing through the second booster conductor, and the third current circulates along the circumference of the first booster conductor. Thus, the antenna apparatus is much less influenced by nearby metallic objects and a shape of an included radiation plate may be more freely determined without requiring a highly accurate positional relationship between the radiation plate and the coil conductor.
