Abstract: An antenna apparatus is provided. The antenna apparatus includes an antenna array including a first plurality of antennas arranged by being shifted in a lateral direction by a distance of an odd integer multiple of a half period of a period of a level fluctuation depending on an antenna lateral position at a first distance that is predetermined as a distance between the antenna apparatus and an antenna apparatus of a communication partner. An antenna apparatus is provided. The antenna apparatus includes an antenna array including a first plurality of antennas arranged by being shifted in a height direction by a distance of an odd integer multiple of a half period of a period of a level fluctuation depending on an antenna height at a first distance that is predetermined as a distance between the antenna apparatus and an antenna apparatus of a communication partner.
