Abstract
An array accommodated in a housing includes multiple antenna elements. The antenna elements face an inside surface of the housing and are arrayed in a first direction at least one-dimensionally. A waveguide is coupled to the antenna elements of the array antenna and extends from the array antenna toward the inside surface of the housing. The waveguide has a housing-side end face facing the inside surface of the housing and an antenna-side end face facing the array antenna. A length from one end to an opposite end of the housing-side end face in the first direction is greater than a length from one end to an opposite end of the antenna-side end face in the first direction. An antenna device that can improve antenna gain without increasing the size of the antenna module is provided.
