Abstract
An antenna apparatus having directivity includes an antenna portion having a power feeding portion, a plate-like first antenna element, and a second antenna element connected to a side of the first antenna element through the power feeding portion, the second antenna element having a width smaller than that of the first antenna element; and a plate-like parasitic element disposed opposite to the antenna portion. The parasitic element has a length that is approximately one-half or more of a wavelength of an operating frequency. The second antenna element has a length that is shorter than one-fourth of the wavelength of the operating frequency. The antenna portion and the parasitic element have a distance capable of being connected electromagnetically to each other.
