| 摘 要： | 针对频率较低时对数周期天线（LPDA）具有较大纵向尺寸，给出以曲线单元作为LPDA 的振子，以实现小型化的方法。采用曲线单元加长了LPDA 振子的电流路径，实现了天线的小型化；通过采用三角、正弦、矩形三种线型单元作为LPDA 的振子，研究了不同线型的小型化效率。对设计的三种线型LPDA 进行了仿真研究，结果表明：用曲线振子作为LPDA 的振子是LPDA 小型化的有效措施，其中矩形线型振子LPDA 相比传统LPDA，尺寸缩小了19%；曲线振子LPDA的小型化效率主要受曲线长度的影响，与振子的形状和宽度也有关系。

| Abstract: | It is presented in this paper that the method of using meander line dipole for miniaturize the size of Log-PeriodicDipole Arrays. The meander line dipole lengthen the current path in order to miniaturize the size of LPDA. And the efficiencies ofminiature is researched by using trigonal, sinusoidal and rectangular meander line dipoles for arms of LPDA respectively. Thesimulation results show that using meander line dipole for LPDA is the effective method of LPDA size miniature, and the lowfrequency of rectangular dipole LPDA is lowered about 19% compared to the conventional LPDA. The miniature efficiency is notonly relative to the length of meander line, but also the linetype and width of the meander line. |
