Abstract
An antenna structure for vehicles capable of minimizing the distance between a first contact member and a signal processing circuit and ensuring stable antenna performance without using a connection line of a lengthy wire rod is provided. To realize this advantage, an antenna element is disposed on a rear window glass, and the first contact member is disposed at an end of the antenna element. Further, an amplifier case having an attachment flange facing the rear window glass is fixed to a roof panel, and the signal processing circuit is disposed in the amplifier case at a position sandwiching the attachment flange.
