An antenna device including a dielectric substrate, a power supply line, a waveguide, a first antenna element, and a second antenna element. The power supply line is disposed on a first surface of the dielectric substrate. The waveguide is configured to transmit a signal fed from the power supply line in the dielectric substrate. The first antenna element is disposed on a second surface of the dielectric substrate and is configured to receive the signal supplied from the waveguide by a first proximity coupling. The second antenna element is disposed on the second surface of the dielectric substrate and is configured to receive the signal supplied from the waveguide by a second proximity coupling.
