The antenna device provided inside a door handle of a vehicle includes a first antenna, a second antenna, a receiver, and an inner case. The first antenna is provided at a grip portion of the door handle, and transmits a radio wave in a first frequency band. The second antenna receives a radio wave in a second frequency band higher than the first frequency band. The receiver processes a signal based on the radio wave received by the second antenna. The inner case accommodates the second antenna and the receiver inside the door handle. In the inner case, the first antenna and the second antenna are arranged along a longitudinal direction of the door handle.
