An on-board antenna device comprises: a radiation element () formed on an inner-surface of a widow glass () for a vehicle (); a base plate () fixed on the inner-surface of the widow glass () so as to surround the radiation element (); a circuit board () having a conductive layer in a surface () thereof, which is opposed to the radiation element (), and a component mounting surface electrically connected to the radiation element () in the other surface () thereof; and a housing () assembled onto the base plate (), and the circuit board () being contained therein; wherein the circuit board () has a cutout portion () to incorporate a connector () for a transmission line connection.

On-board antenna device

A feeding structure of an antenna device formed on a window glass panel of a motor vehicle is provided. A first feeding element opposing to the hot antenna element of the planar antenna and second feeding element opposing to the ground antenna element are located in the module mounted on the window glass panel so as to cover the planar antenna.

Feeding structure of antenna device for motor vehicle and antenna device

A vehicular antenna apparatus includes a radiating conductor directly patterned on a glass surface of a vehicle, a base plate fixed to the glass surface, a frame screwed to the base plate, a power feeding substrate and a circuit substrate accommodated and held in the frame, a connecting small substrate electrically connecting both substrates, and a cover attached on the top of the frame. A patterned surface of the power feeding substrate is close to and faces the glass surface, and thereby indirect power feeding can be performed. Both ends of the connecting small substrate are received in connecting holes. A power feeding pattern and a preamplifier circuit are connected via a microstrip line.
