1. An electronic device comprising:
an array antenna including a plurality of antenna elements;
a transceiver circuit operatively coupled to the array antenna and configured to control a signal of a millimeter wave band applied to the array antenna; and
a processor operatively coupled to the transceiver circuit and configured to:
control a first signal to be radiated to a second electronic device by turning on a transmitting first antenna element of the plurality of antenna elements disposed at a far-left side of the array antenna and control a second signal to be radiated to the second electronic device by turning on a transmitting fourth antenna element of the plurality of antenna elements disposed at a far-right side of the array antenna, wherein a radiation pattern of the transmitting first antenna element is in a first direction and a radiation pattern of the transmitting fourth antenna element is in a second direction opposite to the first direction;
determine a first data rate of the second electronic device based on the first signal radiated through the transmitting first antenna element and a second data rate of the second electronic device based on the second signal radiated through the transmitting fourth antenna element;
select an optimum antenna element based on the first data rate and the second data rate of the second electronic device receiving the signal; and
perform communication with the second electronic device through the selected optimum antenna element,
wherein the first signal is received through a receiving first antenna element disposed at a far-left side of an array antenna of the second electronic device and the second signal is received through a receiving fourth antenna element disposed at a far-right side of the array antenna of the second electronic device.
 
14. A method of performing mmWave band short-range communication in an electronic device, the method comprising:
a signal transmission step in which a transceiver circuit is controlled such that a first signal is radiated to a second electronic device by turning on a transmitting first antenna element of a plurality of antenna elements of an array antenna disposed at a far-left side of the array antenna and such that a second signal is radiated to the second electronic device by turning on a transmitting fourth antenna element of the plurality of antenna elements disposed at a far-right side of the array antenna, wherein a radiation pattern of the transmitting first antenna element is in a first direction and a radiation pattern of the transmitting fourth antenna element is in a second direction opposite to the first direction;
a data rate determining step in which a first data rate of the second electronic device is determined based on the first signal radiated through the transmitting first antenna element and a second data rate of the second electronic device is determined based on the second signal radiated through the transmitting fourth antenna element;
an antenna selection step in which an optimum antenna element is selected based on the first data rate and the second data rate of the second electronic device; and
performing communication with the second electronic device through the selected optimum antenna element,
wherein the first signal is received through a receiving first antenna element disposed at a far-left side of an array antenna of the second electronic device and the second signal is received through a receiving fourth antenna element disposed at a far-right side of the array antenna of the second electronic device to a second direction opposite to the first direction.
