摘　　要：为了研究影响甚低频天线辐射效率的辐射电阻和地损耗电阻,采用数值仿真与差值相结合的方法,对某双副十三塔甚低频伞形天线中的一副天线进行了数值建模,通过与天线实际测量值对比,验证了天线建模的正确性,研究了天线边塔接地前后天线辐射电阻的变化。在简化该模型的基础上,探讨了天线工作在不同频率下,辐射状地网单圈汇流环位置和汇流环数目对地损耗电阻的影响。In combination of the numerical simulation and the difference method, the numerical model of VLF thirteen tower antenna is established, and the comparison of actually measured value with simulated value indicates the correctness of the antenna model. Meanwhile the change of the antenna radiation resistance in or after the grounding of edge tower is studied. Based on the simplified model, when the antenna is operated at different frequencies, the influence of radial ground network on ground loss resistance with the change of ring position and ring number is discussed.
