images.samsung.comThe passive antenna beam pattern of legacy cellular systems is fixed and shaped to transmit its signal uniformly within the coverage direction. On the contrary, an active antenna system (AAS) consisting of multiple antenna elements is able to transmit and receive the signal through beams of a narrow beamwidth and high gain as shown in
