MULTI-BEAM ANTENNA SYSTEM AND METHOD FOR CONTROLLING OUTPUT POWER THEREOF

摘要

Disclosed are a multi-beam antenna system and a method of controlling an output power thereof. An embodiment of the present invention includes a beam forming network configured to receive a plurality of signals to be a plurality of beams, to divide each of the plurality of signals to a plurality of divided signals, and to output a plurality of excited signals by adjusting and combining amplitude and phase of each of the plurality of divided signals, an MPA set having a plurality of MPAs configured to receive corresponding excited signals among the plurality of excited signals from the beam forming network and to control output powers of the received excited signals according to communication traffic, and a feed array having a plurality of feeds configured to form a multi-beam by being excited according to the amplitude and phase of the excited signals from the MPA set.
