Abstract
Disclosed is an antenna apparatus which can control directivity of a plurality of radiation elements using one parasitic element. The antenna apparatus includes two radiation elements arranged on a base parallel to each other, and a parasitic element disposed between the two radiation elements. Radiation directivity of the two radiation elements is controlled according to the length of the parasitic element. This configuration provides a small-sized antenna apparatus including a plurality of radiators with desired directivity.
