论文首先依据矩量法对偶极子天线和对数周期天线上的电流分布进行计算，再根据电流分布得出远场和近场的场强波瓣图，并在此基础上利用一致性几何绕射理论分别计算了天线附近存在电大、电小尺寸导体时天线场强波瓣图的变化。
論文首先依據矩量法對偶極子天線和對數週期天線上的電流分佈進行計算，再根據電流分佈得齣遠場和近場的場彊波瓣圖，併在此基礎上利用一緻性幾何繞射理論分彆計算瞭天線附近存在電大、電小呎吋導體時天線場彊波瓣圖的變化。

Dipole antenna and log‐periodic antennas are analyzed using the method of moment .The antenna is divided into segments and the currents are calculated on each segment ,and the lobe pattern of far‐field and near‐field are obtained through the distribution of current .Furthermore ,the near‐field changes when there are electrically large and electrically small conductors exist near the antenna based on the uniform theory of diffraction are calculated .
