The invention provides a satellite configuration and switching method of a dual-band planar phased-array antenna, the satellite configuration comprises a satellite platform 1, a planar phased-array antenna group and a ground data transmission antenna 5, the planar phased-array antenna group comprises two planar phased-array antennas 2 with different frequency bands, the two planar phased-array antennas 2 are both connected with a top plate of the satellite platform 1, and the two planar phased-array antennas 2 are connected with the ground data transmission antenna 5. The earth data transmission antenna 5 is arranged on one side of a top plate of the satellite platform 1, in a flight state, the two planar phased-array antennas 2 are unfolded until the two planar phased-array antennas 2 are located on the same plane and form a dual-band antenna, and the normal direction of the array surface of the dual-band antenna is consistent with the normal direction of the top plate of the satellite platform 1; the satellite configuration provided by the invention is stable in structure, can bear the effective load of the dual-band planar phased-array antenna, is high in utilization rate of the envelope space of the fairing, and has very high adaptability to the existing satellite adopting the effective load of the planar phased-array antenna of a low-dip-angle orbit.

    本发明提供了一种双频段平面相控阵天线的卫星构型及切换方法,包括卫星平台1、平面相控阵天线组以及对地数传天线5,平面相控阵天线组包括两块不同频段的平面相控阵天线2,两块平面相控阵天线2均连接卫星平台1的顶板,对地数传天线5设置在卫星平台1顶板的一侧,飞行状态时,两块平面相控阵天线2均展开,直至两块平面相控阵天线2位于同一平面且形成双频段天线,双频段天线阵面法向与卫星平台1顶板法向一致;本发明提供的卫星构型结构稳定、可承载双频段平面相控阵天线有效载荷,整流罩包络空间使用率高,对于目前采用低倾角轨道的平面相控阵天线有效载荷的卫星具有很高的适应性。
