Electronic device having antenna array and power backoff control method for the electronic device

A method of controlling power backoff in an electronic device, the method comprising:

• identifying a second number of elements from a plurality of elements in an antenna array that are receiving power to perform beamforming and a third number of the plurality of elements that are not receiving power to perform the beamforming, the second number being less than a total number of the plurality of elements, wherein a first number corresponds to a total number of the plurality of elements;
• determining a first backoff value stored based on a feed polarity of the antenna array and the second number;
• and
• performing a power backoff operation according to the first backoff value.

A non-transitory computer-readable storage medium configured to store one or more computer programs including instructions that, when executed by a processor, cause the processor to control to:

• identify a second number of elements from a plurality of elements in an antenna array that are receiving power to perform beamforming and a third number of the plurality of elements that are not receiving power to perform the beamforming, the second number being less than a total number of the plurality of elements, wherein a first number corresponds to a total number of the plurality of elements;
• determine a first backoff value based on a feed polarity of the antenna array and the second number;
• and
• perform a power backoff operation according to the first backoff value.
