摘要:
为了优化结构和降低成本,将中波天线的密布埋地的地网改为稀疏的架高地网.本文使用矩量法编程计算并给出了架高地网中波天线在不同地网线根数和地网架高时的输入阻抗、辐射方向性图和场强电平,还进一步计算了天线拉线对输入阻抗、辐射方向性图及场强电平的影响.结果表明:当地网线的根数大于3根、架高3~9 m时,中波天线的输入阻抗和场强电平在工程应用可接受范围内; 天线的拉线对输入阻抗、辐射方向性图及场强电平影响不大.
Abstract:
Compared with traditional buried dense radials, the ground system composed of elevated sparse radials is better in both construction and cost. The influence of number and height of radials and the stay wire of the tower of a quarter-wavelength vertical monopole on the impedance, pattern, and electric field intensity are presented, based on an integral equation modal and the method of moment(MoM)analysis. The results show that: when the number of radial N≥3 with the height 3-9 m, the gain and the input impedance of the elevated radials are acceptable in practice; the stay wire of tower only has a little influence.
