摘要
以舰船通信天线为研究对象,应用网格模型分析法及矩量法(MOM)对其进行计算分析,给出了求解复杂天线问题的一般思路。基于Pocklington积分方程和Galerking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。计算结果反映出了船体对舰船天线本身的影响。
The body under study is the communication antenna on warship which is simulated by the wiregrid model and calculated by Method-of-Moments (MOM). How to solve the problems of antenna using this method is also introduced here. Based on the Pocklington integral equation and Galerking method, the input impedance and the radiation pattern of the antenna are calculated by employing the piece wise sinusoidal function as the expansion. In addition, the results are compared with the antenna which is on an infinite surface. The resuits obtained can indicate that the body on which the antenna is set affects the performances of the antenna.
