以舰载短波天线为研究,应用网格模型分析法和矩量法对其进行仿真、计算,给出了求解复杂天线问题的一般思路。基于Pock lington积分方程和G a lerk ing法,采用分段正弦函数展开,计算得出此类天线的输入阻抗和辐射方向图,并与无限大导体平面上的天线进行了比较。计算结果反映出了天线载体对天线本身的影响。 Taking the shipborne shortwave antenna as the research, this paper simulates and calculates it by the method of grid model analysis and moment method, and gives the general idea of ​​solving the complex antenna problem. Based on the Pock lington integral equation and Galerkin method, the input impedance and the radiation pattern of the antenna are calculated by the piecewise sine function, and compared with the antenna on the infinite conductor plane. The calculation results reflect the effect of the antenna carrier on the antenna itself.
