Abstract: The present invention relates to a beam steering device of a phased array antenna for reducing a grating lobe, and more particularly, to a beam steering device of a phased array antenna for reducing a grating lobe so that grating lobes generated when receiving a signal by rotating an array of a plurality of antenna elements at a predetermined angle during transmission do not overlap each other when receiving the signal through the beam steering device.
