摘要： 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.

摘要： To provide a vehicle antenna device which includes multiple antennas, the frequency bands of radio waves to be transmitted and received by the multiple antennas being at least partially different from each other, proximate to each other and which can reduce the degradation of the transmission/reception sensitivity of each of the multiple antennas.
A vehicle antenna device to be mounted on a vehicle, comprising:
a first antenna capable of transmitting and receiving radio waves of a first frequency band; and
a second antenna proximate to the first antenna and capable of transmitting and receiving radio waves of a second frequency band including a frequency band higher than the first frequency band,
wherein at least one of the first antenna and the second antenna is disposed in or on window glass of the vehicle or in the vicinity of the window glass, and
wherein the second antenna includes a power supply unit to which a high-pass filter is connected.-

摘要： 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.
