| 摘 要： | 采用矩量法求解闭合结构的天线问题时可以使用混合场积分方程.然而实际运用中的一些天线常常是一部分结构属于开放结构,一部分结构属于闭合结构.对于这类问题,混合场积分方程并不能保证场解的唯一性,若使用电场积分方程来求解,则产生的阻抗矩阵性态差.因此,对于这类问题我们使用了一种改进的电场积分方程来求解,并用此种方法求解了天线的辐射方向图.文章中给出了算例,结果表明该方法是有效的.

| Abstract: | The CFIE is adopted when using the method of moment to solve the problems of closed structured antenna.In practice,the antenna structure is usually partly closed and partly open.When it comes to this problem,the solution which gets from the CFIE can not be guaranteed as the only solution.If the EFIE is applied to solve this type of problem,the condition of the impedance matrix the EFIE generated is poor.So a method of advanced EFIE is adopted to solve the problem and obtain the antenna direction graph.Numer... |
