Abstract
Abstract A substantially-rectangular-prism-shaped base member is made from at least one of a dielectric material and a magnetic material. A radiation electrode is formed on a surface of the base member such that the electrode is routed from one end face of the base member to the opposing end face through a main surface, changes direction on the end face, and then is routed from the end face to the former end face through the main surface in an almost gate-shaped path. A gap is provided at a part of the radiation electrode, which divides the electrode. With this configuration, a surface mounting antenna is made. This surface mounting antenna is placed on a printed circuit board. One end of the radiation electrode is connected to a power-supplying electrode on the printed circuit board and the other end of the radiation electrode is connected to a ground electrode on the printed circuit board by soldering or adhesion. Then, an antenna apparatus is formed.
