| 摘 要： | 为了减少星载平面反射阵列天线设计所需的庞大计算量,提出了一种基于菲涅尔原理的新的天线布阵方法,该方法通过多种菲涅尔相位环带实现相位补偿,每一环带所用贴片单元一致。在此基础上设计了工作频率为94GHz,由4种菲涅尔相位环带组成的平面反射阵列天线。通过仿真计算,证明该方法合理有效,可应用于星载轴对称平面反射阵天线的设计。

| Abstract: | In order to reduce the computation complexity of the plate reflectarray antenna,the paper presents a new array layout method based on Fresnel principle.Phase compensation is implemented through a variety of Fresnel phase band which have the same type of unit.Based on this technique,a single-layer microstrip plate reflectarray antenna operating at 94GHz has been designed which combines 4 correcting zones in its center.The simulation results verify the feasibility of this design.The method can be used for the design of axisymetric plate reflectarray antenna for satellite. |
