摘　　要：以任意张角的水平对称天线为研究对象,应用矩量法对其进行计算,给出了利用矩量法求解天线问题的一般思路.基于Pocklington积分方程和Galerking法,采用分域积 Dirac函数展开及点匹配模式,计算得出此类天线的电流分布、输入阻抗和辐射方向图,并对不同张角和电长度的水平对称天线进行了比较,在实际使用中可根据不同通信要求对天线进行选择.The random angle of level symmetry antenna which are calculatedby moment methodis studied. Moment methodis introduced and that how to solve the problems of antenna by this methodis alsointroduced. Based on the Pocklington integral equation and Galerking method, the current distribution, the input impedance and the radiation pattern of the antenna by employing point matching method and the piece wise Dirac function as the expansionare got. In addition, the results with different angle of level symmetry antenna and wave-length are analyzed. The results obtained can provide the choices of antenna used on different needs of communication.
