PROBLEM TO BE SOLVED: To provide an antenna device capable of obtaining radiowave radiating angles in a vertical direction which are different for respective frequencies. SOLUTION: In the antenna device in which two or more antennas are arranged in a vertical direction to radiate broadcast waves of two or more different frequencies, a radiowave radiation angle is different depending on a frequency because the lengths of feeders are different by one wavelength or more of one broadcast wave.
