Abstract: An antenna device includes a ground plate that is a plate-shaped conductor member, a patch portion that is a plate-shaped conductor member placed to be opposed to the ground plate with a predetermined distance therebetween, a short-circuit portion that is a conductor member electrically connecting together the patch portion and the ground plate, and an additional conductor that is a plate-shaped conductor member placed to be opposed to the patch portion with a predetermined distance therebetween. The additional conductor is placed on a side of the patch portion on which the ground plate is not placed. An inductance of the short-circuit portion, a capacitance formed by the ground plate and the patch portion, and a capacitance formed by the patch portion and the additional conductor are used to perform parallel resonance.

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.

Abstract: An antenna device includes: a ground plate made of a conductor with a flat plate shape; an opposing conductive plate made of another conductor with a flat plate shape, arranged to space apart from the ground plate by a predetermined distance, and having a power supply point electrically connected to a power supply line; a short-circuit portion electrically connecting the opposing conductive plate and the ground plate; and a radio wave shield body for shielding a propagation of an electric field, which is arranged on an upper side of the opposing conductive plate and is made of a conductor or a dielectric material. Parallel resonance at a predetermined target frequency is generated by an inductance provided in the short-circuit portion and a capacitance between the ground plate and the opposing conductive plate.
