介绍了一种与DJS—1卫星平台及我国卫星测控网相适应的圆极化卫星测控天线。设计充分考虑三化要求,辐射单元采用了能够实现“轴向型”宽波束方向图的小口径喇叭,只要在卫星指地面和背地面各装一副天线,就可组成双向方向图。在喇叭之后加一个正交模耦合器,就可实现正交辐射;在喇叭和馈电部件之间加入一个圆极化器,就可实现圆极化辐射。从而实现了卫星测控天线的模块化和通用化。 A circularly polarized satellite monitoring and control antenna that is compatible with the DJS-1 satellite platform and China’s satellite monitoring and control network is introduced. Design fully consider the three requirements, the radiation unit used to achieve “axial” wide beam pattern of small-caliber speakers, as long as the satellite refers to the ground and back ground each with an antenna, you can form a two-way direction. After the speaker plus a quadrature mode coupler, you can achieve orthogonal radiation; horn and feed components by adding a circular polarizer, you can achieve circularly polarized radiation. In order to achieve the satellite monitoring and control antenna modular and universal.
