Abstract: An antenna device 1 is an antenna device 1 to be mounted on a vehicle including an inner panel 17 that is provided with a mounting hole, and a roof 16 in which a region facing the inner panel 17 on an upper side of the inner panel 17 is upraised to an upper side. The antenna device 1 includes a base 12 and a fixing portion (13, 14, and 15) that fixes the base 12 to the inner panel 17. At least a part of the antenna device 1 is contained in a space 16b formed between a region 16a of the roof 16 that is upraised and the inner panel 17, and there are a plurality of portions in which the base 12 and the inner panel 17 are fixed by the fixing portion.

Abstract: Provided is an antenna device capable of simplifying a structure while preventing degradation of antenna performance even with an upright type double-case structure. An antenna device having a double-case structure includes an inner case inside of which a housing space is formed so as to house a coil element and the like therein, the inner case being covered with an outer case. An antenna element is provided between an outer surface of the inner case and an inner surface of the outer case. The antenna element is electrically connected to the coil element provided in the housing space while keeping water-tightness of the housing space.

Abstract: An antenna device includes: a case; a board which is encased in the case and receives a signal from an antenna element; and a base for which closes a bottom face of the case. The base is integrally provided with a metal fastening member, and includes a sheet metal part for conducting earth connection between an earth electrode of the board and a vehicle panel, and the sheet metal part is surrounded with resin to be integrally molded therewith.
