  • Windowpane for vehicle and antenna
    Patent number: 8941545
    Abstract: A vehicle window glass has a glass plate, a conductive film laminated on the glass plate and an antenna structured with a feeding structure placed on the conductive film, and is characterized in that the feeding structure has a dielectric and a pair of electrodes, that the conductive film has a slot one end of which makes an upper edge of the conductive film an open end, and is disposed between the glass plate and the dielectric, and that the pair of electrodes are disposed on the opposite side of the side of the conductive film with the dielectric in between so that the slot is sandwiched between the pair of electrodes when the pair of electrodes are projected onto the conductive film, and are capacitively coupled to the conductive film.
