摘要

采用宽带耦合结构构建了具有超宽带性能的平面带通滤波器。该设计旨在实现覆盖3.1 GHz至10.6 GHz频率范围的通带，以满足现代UWB室内和室外通信系统的要求。为了实现宽的上阻带，采用了阶跃阻抗谐振器来抑制兴趣带外的谐波响应。给出的结果证实了超通带性能。此外，该器件具有延伸至20ghz以上的宽上阻带，并且。它显示了一个平坦的群延迟，在整个通带的峰对峰变化小于0.1 ns，显示了在脉冲射频系统中工作时的无失真性能。所设计的耦合器尺寸紧凑，为1.2 cm×1.8 cm。

Planar bandpass filter for ultrawideband communication systems

A broadside-coupled structure is used to build a planar bandpass filter with ultra-wideband (UWB) performance. The design is aimed at achieving a passband that covers the frequency range from 3.1 GHz to 10.6 GHz as required by the modern UWB indoor and outdoor communication systems. To achieve a wide upper stopband, a stepped impedance resonator is employed to suppress the harmonic responses outside the band of interest. The presented results confirm ultra passband performance. Furthermore, the device has a wide upper stopband that extends above 20 GHz, and. It shows a flat group delay with less than 0.1 ns peak-to-peak variation across the passband revealing a distortionless performance when operating in pulsed RF systems. The designed coupler has a compact size of 1.2 cm×1.8 cm.
