ABSTRACT:
An antenna device suitably provided in a vehicle is provided with low cost. A receiving module is fixed in the internal space formed by a pair of case parts. The receiving module includes a dielectric substrate, an antenna element provided on one main surface of the dielectric substrate, a ground plate provided on the other main surface of the dielectric substrate, and a circuit board provided on the backside of the main surface having the dielectric substrate at the ground plate, and a shield case that shields the circuit board. The ground plate has an extension extending parallel to the antenna element from the outer peripheries of said dielectric substrate and the circuit board, and the extension is supported in the pair of the case parts, so that the receiving module is fixed in the internal space of the pair of case parts.
