摘要
单元加载是缩小对数周期天线尺寸的方法之一。论述了对数周期天线的单元根部加集中电感负载时的设计思路以及确定单元加载量的方法,并采用矩量法分析了一种加载对数周期天线的性能。研究表明,感性加载是缩小对数周期天线尺寸的一种很有效的方法,该方法扩展了对数周期天线的应用场合。
Element load is one of the methods for reducing log-periodic antenna size. This paper tells of the design idea of the root of antenna unit with lumped inductive load and a method for determining the element load rate. Also, the properties of load log-periodic antenna are analyzed by method of moments. The experiment indicates that the inductive load is an effective method for reducing the log-periodic dipole antenna size, and this method could expand applications of the log-periodic antennas.
