An antenna device for a vehicle includes a camera that facilitates assembly. The antenna device for a vehicle includes: an antenna case that has a housing space formed therein; an antenna base that is covered with the antenna case from above to form the housing space; an antenna element that is held by the antenna base and housed in the housing space; and a camera that is housed in the housing space The antenna base has a wall portion extending upward. The camera is fixed to the wall portion.

Antenna device for vehicle

An antenna device capable of suppressing influence on an antenna performance even if an electronic device is provided in its vicinity is provided. An antenna deviceis equipped with a top elementand a coil. A casingof a camerais disposed at such a position as not to be right under the top element. The coilis disposed close to the casingin a front-rear direction. A distance between the casingand the coilin the front-rear direction is longer than or equal to 0.00075 times a shortest wavelength of a reception target signal. A maximum antenna efficiency of the antenna devicein a predetermined frequency band is higher than or equal to 85% of a maximum antenna efficiency in a case where the camerais not provided.
