Abstract
A vehicle antenna device includes an antenna element, a circuit board, a coil, an amplifier circuit and a fixing portion. The antenna element functions as a capacitive antenna supporting a first frequency band. The circuit board has a power feeding portion that is connected to a power feeding line of the antenna element. The coil is electrically connected to the power feeding portion so that the antenna element has an antenna length supporting a second frequency band. The fixing portion and the antenna element are formed at an edge of the antenna element in order to fix the circuit board to the antenna element at a location close to the position of the coil and far from a position of the amplifier circuit. The fixing portion is provided with a predetermined gap from the coil that is large enough to avoid the influence of coupling with the coil.
