Electronic device including flexible display and method of operating the same

An electronic device comprising:

• a housing including a first structure and a second structure slidably connected to the first structure;
• a flexible display disposed on the first structure and the second structure;
• an antenna structure disposed on the first structure or the second structure;
• and a processor configured to:
• perform a first function related to a first antenna included in the antenna structure,
• display information about the first function on the flexible display, based on a sliding of the first structure, and
• display an object related to the first function in a display region of the flexible display corresponding to a position of the first antenna, based on the sliding of the first structure,
• wherein a state of the electronic device changes between an open state in which the first structure slides with respect to the second structure and a closed state in which the first structure does not slide with respect to the second structure,
• wherein, when the electronic device is in the open state, the flexible display is located on a front side of an area where the antenna structure is located and the flexible display is not located on a back side of an area where the antenna structure is located, and
• wherein, when the electronic device is in the close state, the flexible display is located on the front side and the back side of the area where the antenna structure is located.
