We present systematic analysis and planning of multi-beam antenna based on the features of LEO communication satellite. First, the reasons for adopting multi-beam antenna system are analyzed. Calculations of system parameters within the satellite coverage range are performed based on 7-beam equal-coverage-area scheme. System parameters, like beam width and beam angle, are given. Then, the scheme of array antenna is elaborated and analyzed. Some beamforming and multiplexing schemes are designed and analyzed.
