Research on the Architecture of Phased Array Antenna of LEO Communication Satellites Based on Hybrid Beamforming
Due to the characteristics of low earth orbit (LEO) communication satellite system like low propagation loss, small propagation delay and high pointing accuracy, a hybrid architecture-“analog beamforming stage and digital beamforming (DBF) stage” was proposed, and the principle and advantages of hyb...

| description | Due to the characteristics of low earth orbit (LEO) communication satellite system like low propagation loss, small propagation delay and high pointing accuracy, a hybrid architecture-“analog beamforming stage and digital beamforming (DBF) stage” was proposed, and the principle and advantages of hybrid beamforming were analyzed.Through three dimensional integrating of multi-channel RF frontend chips, mixers, dedicated DBF ASIC chips, and tiles phased array anntena arrays, the proposed hybrid beamforming could be expanded or spliced.This hybrid architecture achieved the optimization of performance, cost, complexity and power consumption, and provided a reference for China to build space based internet of things system and reconfi gurable phased array antenna system in the future. |
