Antenna apparatus, system, communication apparatus, data processing apparatus, and computer readable storage medium

A communication apparatus mounted to a movable object, the communication apparatus comprising:

• an antenna array including a plurality of antennas;
• a distance acquisition unit which acquires a distance between a movable object to which the communication apparatus is mounted and a movable object to which a communication apparatus of a communication partner is mounted;
• and
• an antenna control unit which controls positions of the plurality of antennas to be 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 the distance acquired by the distance acquisition unit, and controls positions of the plurality of antennas to be 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 the distance acquired by the distance acquisition unit.

A non-transitory computer readable storage medium having stored thereon a program that causes a computer to function as a communication apparatus mounted to a movable object, the communication apparatus comprising:

• an antenna array including a plurality of antennas;
• a distance acquisition unit which acquires a distance between a movable object to which the communication apparatus is mounted and a movable object to which a communication apparatus of a communication partner is mounted;
• and
• an antenna control unit which controls positions of the plurality of antennas to be 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 the distance acquired by the distance acquisition unit, and controls positions of the plurality of antennas to be 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 the distance acquired by the distance acquisition unit.
