  It is difficult to obtain widefrequency band for traditional band-pass filter with open-loop resonators. The open-loop DGS resonators can increase the coupling coefficient between theresonators and can be used to design wide-band band-pass filters.

  传统开口环结构的带通滤波器很难满足宽频带的要求，开口环结构的DGS谐振器可以有效提高谐振器间的耦合系数，从而可用于设计宽带带通滤波器。
