Abstract
An antenna apparatus has improved gain, and its characteristics are barely affected by changes in the external environment in which it used, such as when it is placed close to a ground conductor. A surface-mount antenna and a monopole antenna are fed by a single feeding point, and the direction of an open end of the surface-mount antenna, taking a ground end of a radiation electrode as a reference, runs opposite to the direction of the open end of the monopole antenna, taking the feeding terminal as a reference.
