摘　　要：混合位积分(MPIE)是矩量法中常用的积分方程之一,它的优势在于可以有效地处理端接负载的问题。本文中,我们将MPIE与半三角基函数相结合,对具有端接匹配负载的长线天线进行分析。这种方法的创新点在于可以利用半三角基函数对模型的边界进行有效处理,从而使得电流通过边界,这样在计算过程的阻抗矩阵只有第一行和第二行的元素需要计算,其他的元素由对称性原理可以方便得出。用这种方法计算所得的沿线电流、电压和辐射方向图与理论值相吻合。证明了所采用方法的正确性,为今后处理更复杂的天线模型开辟了一个新的途径。In this paper, the method mixed potential integral equation （MPIE） combined with half rooftop basis function is used to analyze the long-wire antenna with matched loading terminations. MPIE is a kind of integral equations in Method of Moment （MOM） and can effectively deal with models with terminal loads. The contribution of this method is that we can take proper measures to the boundaries of the model by using the half basis function,which allows the current to flow across the edges. All of the elements in MoM impedance matrix,only the ele- ments in the first and second rows need calculating for the structure of straight line according to the principle of reciprocity and symmetry. The results of current, voltage along the llne and the radiation field calculated by this method agree well with the results of theoretical value and transmission-line theory（TL）.
