ABSTRACT:
An antenna apparatus includes a substrate having a GND pattern land and an electric power feed pattern land on a same surface, an outer element extending away from the land in a spiral shape, and an inner element extending along an axis of the outer element in a spiral shape with a space interposed between itself and the outer element. The outer element and the inner element of the antenna apparatus respectively serve as one of a signal line and a GND line, and are supported by a retainer member to have predetermined relationship on a land formation surface. The retainer member is made of dielectric body, and the two elements respectively have a surface mount portion at one end that is to be fixed onto the substrate with electrical connection to corresponding lands. The surface mount portions are formed substantially parallel to the land formation surface.
