摘要
将微带线/共面波导混合结构与螺旋型缺陷接地结构结合,设计了通带范围3.1~10.6 GHz的超宽带带通滤波器,获得了双通带的滤波特性。采用仿真的方法讨论了缺陷接地结构的尺寸与传输特性的关系。结果表明,新型的双通带带通滤波器具有一定的实用价值。
Hybrid microstrip/coplanar waveguide (CPW) structure is combined with spiral-shaped defected ground structure ( DGS ) to construct a novel ultra-wideband ( UWB ) band pass filter with its pass band coveting the entire UWB band (3.1 - 10.6 GHz ) .The new circuit gains a dual-pass band filtering property.The relationship between the size of DGS and its transmission property is studied by using the electromagnetic simulation.Those results show that the new circuit is more flexible for use.
