摘要: 为拓展带通滤波器的通带带宽,设计了一种基于EBG结构的基片集成波导(SIW)超宽带带通滤波器.该滤波器利用箭头形电磁带隙结构的阻波特性,将不同大小箭头形结构单元蚀刻在SIW上金属面,以获得超宽带通带.所设计的滤波器中心频率在985 GHz,相对带宽为3959%,通带内的最大插入损耗约为154 dB,相比于类似结构的带通滤波器,其带内回波损耗较大,且整体电路面积较小.测量结果与仿真结果基本吻合,有效地验证了该设计方法的有效性.

Abstract: To improve the bandwidth of bandpass filter, a new arrowheadshaped electromagnetic band gap (EBG) ultrawideband bandpass filter based on substrate integrated waveguide (SIW) was proposed. The filter was designed based on the bandstop characteristics of EBG and had obtained ultrawideband by etching different dimensional arrowhead on the surface of substrate integrated waveguide. The ultrawideband bandpass filter with a center frequency at 985 GHz and relative fractional bandwidth 3959% showed good bandpass characteristics, while the insertion loss was less than 154 dB. Compared with similar bandpass filter, the return loss of the filter in the passband is better than others with much smaller circuit size. The good agreement between the measured results and the simulation results demonstrates that the design of this proposed filter is effective.
Key words: electromagnetic bandgap (EBG)    ultra-wideband bandpass    substrate integrated waveguide (SIW)
