Abstract: An antenna device with an attachment member includes an antenna including a radiation plate provided with radiation face that radiates vertically polarized waves, a housing portion that houses the antenna, an attachment member that attaches the housing portion to a vehicle, and a metal fixing portion that is formed in an elongated shape to one end of the attachment member, that abuts a back face of the housing portion facing toward an opposite side to the radiation face, and that fixes the housing portion. Viewed from a thickness direction of the radiation plate, the fixing portion is disposed between a first region formed to the back face on one side in the extension direction of a first straight line, and a second region formed to the back face on another side in the extension direction of the first straight line.

Abstract: An antenna device comprises a dielectric substrate, an antenna including a radiation plate and a ground conductor plate, a connector, and cover member. A position of a feeding point on the radiation plate is different to a position of a centroid of the radiation plate in front view of the antenna, and the antenna and the cover member cover a periphery of the connector when the antenna, the connector, and the cover member are viewed along a direction orthogonal to a first straight line connecting the centroid to the feeding point and orthogonal to a thickness direction of the dielectric substrate.

Abstract: An antenna system for vehicle includes a vehicle and a MIMO antenna that is mounted on the vehicle and that transmits and receives radio waves of a predetermined frequency. The MIMO antenna includes antennas including a first antenna that mainly transmits and receives a first polarized wave and a second antenna that mainly transmits and receives a second polarized wave orthogonal to the first polarized wave, and the antennas are dispersedly arranged on the vehicle. One of the first antenna and the second antenna are arranged based on at least one of (1) a configuration in which one is arranged in a central region and another one is arranged in a first peripheral region or a second peripheral region and (2) a configuration in which one is arranged in a first region and another one is arranged in a second region.
