本文提出了一种基于脊形谐振器的超宽带基片集成波导滤波器。该滤波器依赖于基片集成波导脊形谐振器的设计。梳状谐振器使滤波器能够实现UWB特性。通带的上沿可以通过脊形谐振器中的小杆的宽度容易地调节。一个参数的研究，以显示如何可以调整带宽。测量结果表明，在3.1-10.6 GHz的频带内，反射系数优于-14 dB。通带内最大插入损耗约为1dB。此外，阻带从11.4到17.4 GHz的抑制幅度优于47 dB已经实现。
In this letter, an ultra-wideband (UWB) substrate integrated waveguide (SIW) filter using ridge resonator is presented. The filter relies on designing SIW ridge resonator. The comb-shaped resonator makes the filter to be realizable for UWB characteristics. The upper edge of the passband can easily be adjusted by the width of small rod in the ridge resonator. A parametric study is done to show how bandwidths can be adjusted. The measurement results show that a reflection coefficient of better than −14 dB has been obtained over the frequency band of 3.1–10.6 GHz. The maximum insertion loss in passband is almost 1 dB. Moreover, a stopband from 11.4 to 17.4 GHz with a suppression magnitude better than 47 dB has been achieved.
