Abstract

This study presents an original parallel connected hybrid microstrip-substrate integrated waveguide (PCHM-SIW) bandstop filter. A low-pass filter implemented on a microstrip structure and a SIW-based high-pass filter are connected in parallel to each other. In this way, the aim is to obtain a bandstop filter in the novel hybrid design. The parallel connected hybrid microstrip-substrate integrated waveguide (PCHM-SIW) bandstop filter is synthesised, simulated, and produced. The effects of connecting filters in parallel are discussed. It is seen from the results of CST Studio Suite simulation that PCHM-SIW bandstop filter has a bandwidth of 2.85 GHz and a center frequency of 4.26 GHz. The frequency change rate of the center frequency between simulation and measurement is 7.02 % where it is just 3.76 % for the deviation in bandwidth. The results of the simulation and those of the measurement are close to each other. These results converge to ideal analytical results.

并联混合微带-基底集成波导带阻滤波器

本研究提出了一种独创的并联混合微带-基底集成波导（PCHM-SIW）带阻滤波器。在微带结构上实现的低通滤波器和基于 SIW 的高通滤波器相互并联。这样，新型混合设计就能获得带阻滤波器。我们合成、模拟并制作了并联混合微带-基底集成波导（PCHM-SIW）带阻滤波器。讨论了并联滤波器的效果。从 CST Studio Suite 仿真结果可以看出，PCHM-SIW 阻带滤波器的带宽为 2.85 GHz，中心频率为 4.26 GHz。模拟与测量之间的中心频率变化率为 7.02%，而带宽偏差仅为 3.76%。模拟结果和测量结果非常接近。这些结果趋近于理想的分析结果。
