1. A first array antenna capable of steering a beam in a first communication node of a wireless communication system, the first array antenna comprising:
a plurality of single antennas each capable of variably adjusting a beam steering direction;
a plurality of beamforming control units each of which is connected to each of the plurality of single antennas to control a beamforming operation of each of the plurality of single antennas; and
an array antenna control unit connected to the plurality of beamforming control units to control a beamforming operation of the entire first array antenna,
wherein the plurality of single antennas are arranged in a cylindrical shape and are installed to face a direction opposite to a central direction of the cylinder shape, and the first array antenna is configured to steer a beam to a predetermined area around the first communication node through at least one single antenna among the plurality of single antennas.
