Electronic device comprising antenna

An electronic device comprising:

• memory, including one or more storage media, storing instructions;
• an antenna;
• wireless communication circuitry configured to communicate with an external electronic device using a signal on a designated frequency band;
• a foldable housing including a first housing part and a second housing part rotatably coupled to the first housing part;
• a flexible display including a first portion disposed on the first housing part, a second portion disposed on the second housing part, and third portion between the first portion and the second portion;
• a hinge structure rotatably connecting the first housing part and the second housing part with respect to a folding axis;
• and
• one or more processors, including processing circuitry, communicatively coupled to the wireless communication circuitry and the memory,
• wherein the hinge structure is configured to transition the electronic device among:
• a first state, in which a first direction in which the first portion faces is the same as a second direction in which the second portion faces,
• a second state, in which the first direction is opposite to the second direction, and
• a third state, which is between the second state and the first state, and
• wherein the instructions, when executed by the one or more processors individually or collectively, cause the electronic device to:
• based on the wireless communication circuitry performing communication with the external electronic device, identify an angle between the first portion and the second portion in which upward directivity of a radiation pattern of the antenna is high, and
• display a screen on the flexible display for guiding the angle in which the upward directivity of the radiation pattern of the antenna is high.
