Here, we discuss the virtues of glide symmetry for designing low-frequency band-pass periodic filters in substrate integrated waveguide (SIW) technology based on complementary split-ring resonators (CSRRs). Conventional (non-glide) versions of these filters have a narrow passband, due to the fact that this band is below the cutoff frequency of the background waveguide. When glide symmetry is added to the filter configuration, the low-frequency passband is significantly widened, as well as the first stopband. The dispersion properties of both conventional and glide-symmetric periodically loaded waveguides are analyzed and compared with commercial software and an equivalent circuit model. Finally, two prototypes of the proposed glide-symmetric structure have been designed and built, illustrating the potential of this technique to widen the passband and reduce insertion losses of conventional sub-wavelength CSRR-loaded SIW filters.

基于亚波长谐振器的滑动对称SIW滤波器的通带展宽

在这里,我们讨论了基于互补开口环谐振器(CSRR)的基板集成波导(SIW)技术中设计低频带通周期滤波器的滑行对称的优点。这些滤波器的常规(非滑动)版本具有较窄的通带,这是因为该带低于背景波导的截止频率。当将滑行对称性添加到滤波器配置时,低频通带以及第一个阻带都将显着加宽。分析了常规和滑动对称周期性加载的波导的色散特性,并与商业软件和等效电路模型进行了比较。最后,设计并制造了所提出的滑行对称结构的两个原型,
