Abstract
An antenna device that is built inside a hollow body fixed to a vehicle comprises a composite antenna element that has an antenna length corresponding to a first frequency band and is bent so as to also function as a capacitive antenna corresponding to a second frequency band and to improve an antenna effective capacitance and that is disposed in a substantially planar manner. The composite antenna element is disposed such that a planar direction thereof is inclined toward a vertical-direction side with respect to a metal body of the vehicle, and is offset-disposed to a left or right side in the hollow body with respect to a vehicle traveling direction, and is grounded in a metal portion of the vehicle near a position where the composite antenna element is disposed.
