Abstract
(EN)
The present invention relates to a mobile terminal supporting beamforming and, more particularly, to a mobile terminal that transmits or receives signals in a beamforming scheme using an array or multiple antennas, the mobile terminal comprising: a plurality of antennas; a plurality of low noise amplifiers connected respectively to the plurality of antennas, and amplifying signals received from the connected antennas; a sensing unit for sensing received signal strength of the signals received from the plurality of antennas; and a gain control unit for attenuating at least one amplification gain from among the plurality of low noise amplifiers when the strength detected by the sensing unit is equal to or greater than a preset level.
