摘　　要：将相互耦合的天线视为辐射体和加载散射体,采用矩量法计算天线和耦合天线的电流分布,由源和加载段的电流算出天线间的耦合度。根据以上方法,对短波基站常用的40 m水平双极天线和10 m鞭天线在各种典型架设方式下的耦合度进行了计算。计算结果表明,两副天线采用相互正交的极化和对称布局可显著减小耦合度。The coupled antennas were regarded as a structure with radiators and loaded scatters. Method of moment was used to calculate the currents of antennas. The mutual coupling of two antennas could be educed from the currents of the source segment and the loaded segments. The coupling of the widely-used 40 m dipole and 10 m whip at HF base station were computed in typical layout styles. The computed results show that the mutual coupling of two adjacent antennas can be reduced obviously by using symmetrical layout style and making these two antennas have vertical polarization.
