Abstract
In one embodiment, a coupler apparatus includes a monopole type coupling element, a parasitic element, and a ground plane. The coupling element includes a conductive material and subjects to power feeding to a feeding point. The parasitic element includes a conductive material. The parasitic element is arranged to be apart from the coupling element, and grounded. The ground plane includes a conductive material. The ground plane faces the coupling element and the parasitic element. The ground plane is cut out at a position where it faces at least a part of a portion other than the feeding point in the coupling element or near this position.
