PROBLEM TO BE SOLVED: To provide a thin antenna device ensuring a high gain while keeping a wide beam angle.SOLUTION: The antenna device includes a first horn antenna having a first square waveguide 12 and a first horn 14 having a width widened only on one side and radiating a first sector beam, and a second horn antenna having a second square waveguide 13 and a second horn 15 having a width widened only on one side and radiating a second sector beam. The first horn antenna and second horn antenna are arranged adjacently in a direction of small interference between the first sector beam and second sector beam. |
