针对偏馈式构架天线应用需求，提出一种侧边约束的构架反射器实现方案。结合构架反射器曲面六边形几何特点，进行了反射器整体几何构型设计，并采用局部坐标法完成了桁架零部件的具体构型设计，形成系统的偏馈式构架反射器构型设计方法。根据某型号天线具体参数要求，完成了5.5 m偏馈式构架反射器样机构型设计；通过仿真分析和地面试验对样机展开协调性进行研究，进一步论证了所提出反射器构型设计方法的正确性。
Based on the application requirement of offset-fed truss antenna, a truss reflector with one edge constrained is proposed. Considering the hexagonal outline characteristics of the truss reflector, the overall configuration design is performed, and the detail configurations of the reflector parts are confirmed with local coordinates approach. Then, the configuration design method of offset-fed truss reflector is formed. According to certain antenna parameters, the configuration design of the truss reflector with 5.5 m diameter is performed. The deployment simulation and ground test are carried out, which demonstrate the feasibility of proposed design method
