1. An electronic device comprising:
a signal generator;
a mounting unit on which a device under test (DUT) is disposed, the DUT being electrically connected to the signal generator to form a beam toward a first direction and directions rotated by a first angle based on the first direction;
a plurality of antennas disposed at a position corresponding to the first direction from the DUT and positions corresponding to directions rotated by twice the first angle from the DUT based on the first direction and receiving a signal emitted from the DUT;
a signal meter configured to measure an intensity of a signal received from at least one of the plurality of antennas; and
a control circuit electrically connected to the DUT, the signal generator, and the signal meter,
wherein the control circuit is configured to:
control the signal generator to generate a specified signal and transmit the specified signal to the DUT;
control the DUT to form a beam in any one direction of the first direction and the directions rotated by the first angle based on the first direction and emit the specified signal by using the formed beam; and
check an antenna performance of the DUT based on at least the intensity measured from the signal meter.
