| Abstract: | 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. |
