Antenna device

Abstract

An antenna device includes a substrate, a ground plate, a first element, and a second element. The substrate is a plate-shaped dielectric. The ground plate is a plate-shaped conductor provided on or inside the substrate. The first element is a liner conductive element extending along the surface of the substrate. The second element is a liner conductive element having a three-dimensional shape. The second element includes a standing portion perpendicular to the substrate and a substrate parallel portion extending from an upper end of the standing portion in a direction parallel to the substrate. The substrate parallel portion includes a portion that is parallel to a part of the first element. One of ends: a lower end of the standing portion and an end of the first element, is connected to a feed line, and another of the ends is electrically connected to the ground plate.
