Abstract
A structure for feeding a planar antenna formed on the surface of a window glass panel for a motor vehicle is provided. A dielectric substrate fixed in the module is mounted on the window glass panel so as to cover the planar antenna. A first capacitive feeding element opposed to the hot antenna element and a second capacitive feeding element opposed to the ground antenna are provided on the surface of the dielectric substrate at an antenna side. The planar antenna is fed through these antenna feeding elements. Air is present between the dielectric substrate and the planar antenna.
