Antenna device for vehicle, control method therefor and recording medium for storing program for performing method

A method of controlling a vehicle antenna apparatus including an array antenna including a plurality of antenna elements and installed in a vehicle, the method comprising:

• obtaining, based on a sensing result of a sensor for detecting a position of a user riding in the vehicle, information about the position of the user;
• adjusting, based on the information about the position of the user, a phase of at least one radio wave signal such that a position of a radiation pattern formed by the at least one radio wave signal output from the plurality of antenna elements and the position of the user riding in the vehicle vary from each other;
• and
• controlling the array antenna to output the at least one phase-adjusted radio wave signal.

A server comprising:

• a communicator configured to communicate with a vehicle antenna apparatus installed in a vehicle;
• and
• at least one processor configured to perform at least one instruction,
• wherein the at least one processor, when executing the at least one instruction, is further configured to:
• receive information about a position of a user corresponding to a sensing result of a sensor for detecting the position of the user riding in the vehicle,
• obtain, based on the information about the position of the user, phase information comprising phase values of at least one radio wave signal set such that a position of a radiation pattern formed by the at least one radio wave signal output from a plurality of antenna elements included in an array antenna of the vehicle antenna apparatus and the position of the user riding in the vehicle vary from each other, and
• control the communicator to transmit the obtained phase information to the vehicle antenna apparatus.
