Abstract: An antenna device includes an array antenna configured to radiate a radio wave. The array antenna includes at least four radiating elements arranged substantially parallel to a beam scanning plane of the radio wave. The at least four radiating elements are arranged substantially parallel to a first principal surface of window glass for a building, with the antenna device arranged such that the array antenna is arranged at the first principal surface of the window glass in a non-contact manner and such that the radio wave is radiated toward a second principal surface of the window glass opposite from the first principal surface.

Abstract: A vehicle antenna includes a conductor plate, a radiator plate facing the conductor plate, a feeding portion located on a same side as the conductor plate with respect to the radiator plate, a connection conductor connecting the feeding portion and the radiator plate, and a first element and a second element arranged away from each other on both sides in a vehicle-width direction of a vehicle with respect to the radiator plate, wherein the radiator plate is arranged at an inclination of equal to or less than ±15 degrees with respect to a vertical plane perpendicular to a horizontal plane.

Abstract: There is provided a simple configuration capable of feeding power to a conductor present between a pair of dielectric plates.
A feeding structure including a first dielectric plate; a second dielectric plate that faces the first dielectric plate; an interlayer that is disposed between the first dielectric plate and the second dielectric plate; a conductor that is disposed between the first dielectric plate and the second dielectric plate; a feeding portion that is disposed on a side opposite of the interlayer from the first dielectric plate and that sandwiches at least one of a portion of the interlayer and a portion of the second dielectric plate between the conductor and the feeding portion; and a first transmission line that is connected to the feeding portion, wherein the feeding portion electromagnetically couples to the conductor with a gap smaller than a thickness of the first dielectric plate.
