| Abstract: | This paper mainly focuses on the technology of the multi-beam antenna on the GEO （Geostationary Earth Orbit） mobile communication satellite. The relative technologies wave studied,including the contour of the satellite composite multi-beam antenna,the gain of the beams and the interference controlling among the beams. With the help of software,some antenna system parameters can be optimized. Consequently,the beams isolation is increased,which improves the whole communication systems capability. Finally,it was realized that the composite multi-beam antenna design on the GEO mobile communication satellite is completecl. |
