摘　　要：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。The body under study is the HF antenna on warship which is simulated by the wire-grid model and calculated by Moment Method. The way to solve the problems of antenna by this method was also introduced here. Based on the Pocklington integral equation and Galerking method, the input impedance and the radiation pattern of the antenna were calculated by employing the piece wise sinusoidal function as the expansion. In addition, the results were compared with the antenna which is on an infinite surface. The results obtained indicate that the body on which the antenna is set affects the performances of the antenna.
