Abstract: An antenna device includes a first antenna element and a second antenna element. The first antenna element operates at a first predetermined frequency band. The second antenna element operates at a second predetermined frequency band that is different from the first predetermined frequency band. The first antenna element includes a base end portion, a front end portion, a folded portion, a first side portion disposed between the base end portion and the folded portion, and a second side portion disposed between the folded portion and the front end portion. A direction of a current vector in the first side portion is equal to a direction of a current vector in the second side portion. The second antenna element is disposed adjacent to the first antenna element.

Abstract: An antenna apparatus includes a conductive ground pattern formed on a planar substrate and a linear antenna element electrically connected with the ground pattern. The antenna element includes a base end portion, a front end portion, and a feeding point. The antenna element is parallel to the substrate, and the base end portion is connected with an end portion of the ground pattern so that the antenna element is away from the ground pattern. An auxiliary ground pattern having the same potential with the ground pattern is disposed on the substrate between the ground pattern and the antenna element along a side including the end portion.
