ABSTRACT:
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.
