Method of beamforming in electronic device and electronic device

An electronic device comprising:

• an antenna module;
• a memory;
• and
• at least one processor configured to:
• in response to modulating a signal for transmitting by a first carrier frequency, identify a beam book corresponding to the first carrier frequency stored in the memory, the beam book including information related to a phase corresponding to each of antenna elements included in the antenna module,
• perform beamforming based on the identified beam book via the antenna module,
• in response to modulating the signal for transmitting by a second carrier frequency different from the first carrier frequency, identify a phase compensation value per antenna element, determined based on the second carrier frequency from each phase value included in the beam book, and
• perform beamforming based on the identified phase compensation value per antenna element, via the antenna module.
