详细阐述平面螺旋天线阵列，利用其具有效率高、旁瓣低和受环境等影响小等优点改善其整体性能。选择小螺旋作为Ku波段的螺旋阵列天线的辐射阵元，利用基于FDTD算法的GEMS软件仿真，调节螺旋参数满足天线设计指标，借助仿真结果确定天线阵列的几何参数，并对其进行测试。通过调试得到优化的结果，基于仿真结果与实测结果进行分析加工和重设计，以组成更大的天线阵列，满足实际需要。

This article elaborates on the array of planar spiral antenna,which improves overall system performance due to its high efficiency ,low sidelobe and capability of less susceptible to environmental impacts. Our approach uses the small spiral as the Ku-band helical array antenna radiation array element. GEMS simulation is based on FDTD algorithm. Spiral antenna parameters are adjusted to meet the design target. Simulation results can help to determine geometry parameters of the antenna array and test it. With debugged and optimized results ,the paper analyzes and re-designs the simulation results and experimental results to form a larger antenna array and meet actual needs.
