Abstract

To address the long distance and significant loss in satellite-to-ground wireless link

new demands are imposed on satellite phased arrays by direct-to-handset satellite. By analyzing the practical requirements of direct-to-handset satellite

the advantages and disadvantages of various beamforming architectures were outlined

then the proper selection strategy of beamforming architecture was proposed. Subsequently

dual-band shared-aperture circularly-polarized antenna arrays under frequency division duplexing (FDD) were discussed. In addition

the stacking and integration architecture of phased arrays was reviewed

and several key fabrication technologies for components and chips were introduced. Finally

the outlook and key technologies of satellite phased arrays for direct-to-handset satellite were presented.
