Abstract
An antenna device has a configuration in which a feeding point is located at a position that is distant from an outer periphery of a ground conductor plate to a center side and that would correspond to polarized waves parallel to the ground conductor plate. The antenna devices includes a ground conductor plate and an antenna element. The antenna element includes a first vertical portion and a second vertical portion which are erected substantially perpendicularly from the ground conductor plate and a first parallel portion, a second parallel portion, and a third parallel portion which extend substantially parallel to the ground conductor plate. An end portion, in the −Z direction, of the first vertical portion serves as a feeding point and is located at a position that is distant from an outer periphery of the ground conductor plate to a center side.
