摘要
为了实现带线印刷对数周期偶极天线的小型化,本文采用一种矩形电容贴片的单元作为该天线的谐振单元,实现了该天线的小型化。文中对该贴片单元的各种设计参数的设计原则进行了计算和分析,根据分析结果设计了尺寸减缩比为0.7的小型化对数周期偶极天线和普通印刷对数周期偶极天线,进行了驻波比和方向图的测试,测试结果表明这种方法没有带来性能的剧烈恶化,是一种有效的小型化方法。
In order to realize the miniaturization of the stripline log periodic dipole arrays, a unit of the rectangle electric capacity patch is adopted as the resonance unit of this aerial in this paper. Various of this unit of different design parameters were calculated and analysed, then got the design principles of size-reduction. A 70% miniaturization ratio stripline log periodic dipole arrays was designed and fabricated. The VSWR and pattern of this antenna were measured, The test result indicates that the performance is not deteriorate. So it is a kind of effective miniaturization method.
