Method for detecting blockage and electronic device thereof

A portable communication device comprising:

• a first antenna array including a first antenna and a second antenna;
• a second antenna array including a third antenna and a fourth antenna;
• a first radio frequency integrated circuit electrically connected with the first antenna array;
• a second radio frequency integrated circuit electrically connected with the second antenna array;
• and
• a processor electrically connected with the first radio frequency integrated circuit and the second radio frequency integrated circuit;
• wherein the first radio frequency integrated circuit is configured to:
• transmit a first signal to an outside of the portable communication device via the first antenna;
• and
• receive, while the first signal is transmitted via the first antenna, a second signal corresponding to the first signal via the second antenna, and wherein the processor is configured to:
• determine whether the second signal satisfies a specified condition to determine blockage of the first antenna array,
• if the specified condition is not satisfied, perform a beam forming using the first radio frequency integrated circuit;
• and
• if the specified condition is satisfied, perform a beamforming using the second radio frequency integrated circuit and the second antenna array.
