Zusammenfassung:	A beamforming apparatus and a beamforming method using an expandable planar array antenna are provided. The beamforming apparatus that performs the beamforming method includes an array antenna in which an Elevation (EL) antenna group configured to perform beam steering in an elevation angle direction and an Azimuth (AZ) antenna group configured to perform beam steering in an azimuth angle direction are disposed on a same plane, a first chip located on a top surface of the array antenna and configured to control the beam steering in the elevation angle direction by controlling patch antennas included in the EL antenna group, and a second chip located on a bottom surface of the array antenna and configured to control the beam steering in the azimuth angle direction by controlling patch antennas included in the AZ antenna group.
