A window member includes a transparent substrate, wherein in plan view of the window member, the transparent substrate itself includes a first region, and a second region having higher radio-wave transmissivity than the first region. The transparent substrate may include a first glass sheet, and a second glass sheet which is laminated to the first glass sheet via an intermediate film.

Window member and vehicle window glass

A glass antenna placed in a window glass for a vehicle includes a second antenna that includes a second power feeding point, and a second element connected to the second power feeding point; a third antenna that includes a third power feeding point, and a third element connected to a third power feeding point; and a no-power-fed element that includes a first overlapping part placed in parallel with at least a part of the second element, separated by a third interval, and a second overlapping part placed in parallel with at least a part of the third element, separated by a fourth interval.

Glass antenna and window glass for vehicle

A vehicle window glass includes a glass including a transparent area and a shading area around the transparent area; a defogger including wires placed at equal first intervals extended in a direction, and a defogger element connected to the wires; and a glass antenna including a power feeding point in the shading area, and a first element connected to the power feeding point. The defogger element includes a first part in the transparent area and extended in the direction, and a second part in the shading area and connected to the first part. The first element includes a third part in the transparent area extended in the direction, and a fourth part in the shading area and connected to the third part and the power feeding point. A part of the second part and a part of the fourth part are placed to have a narrower interval.

Window glass for vehicle

The present invention relates to a vehicular antenna apparatus including: a dielectric substrate; an antenna provided to the dielectric substrate; and a connector electrically connected to a feeding cable of a receiving apparatus, in which the antenna includes an antenna conductor provided to the dielectric substrate, and a feeding electrode electrically connected to the antenna conductor and provided on a first surface of the dielectric substrate, the connector includes a connector main body supporting the feeding cable, and a terminal electrode provided to the connector main body and electrically connected to the feeding cable, and the feeding electrode and the terminal electrode are joined via an insulating adhesive, thereby being capacitively coupled with each other.

Vehicular antenna apparatus and connector for vehicular antenna apparatus

A glass antenna placed in a window glass for a vehicle includes a first antenna that includes a first power feeding point, and a first element connected to the first power feeding point; a second antenna that includes a second power feeding point placed next to the first power feeding point, and a second element connected to the second power feeding point; and a third antenna that includes a third power feeding point placed next to the second power feeding point, and a third element connected to the third power feeding point and having a longest path longer than respective longest paths of the first element and the second element, and wherein at least a part of the third element is placed between the first element and the second element.
