摘　　要：基于Wu-King理论,提出了一种双指数形的天线电流分布,推导出高效电阻加载分布;理论研究了采用这种加载分布的线天线的电特性,并与Wu-King加载做了比较,同时给出了加载天线的最佳参数设计曲线。计算表明采用这种加载分布可以显著地提高天线的带宽和效率。Based on Wu-King＇s theory, the author proposed the double exponential current distribution of antenna, deduced an high efficiency resistive loading profile. The electrical properties of the high efficiency loading antenna were studied theoretically; the optimum parameter design curve of the antenna was provided. Theoretical calculation shows that the improved resistive loading antenna exhibits better bandwidth and efficiency than Wu-King antenna.
