| 1. | Two kinds of filters are presented : by transferring the conventional waveguide cavity filter to the siw , a narrow bandstop filter is designed and simulated , get characteristic of narrow - band bandstop filtering . for example , relative bandwidth 1 . 2 % , most attenuation of 48db in band . electromagnetic bandgap ( ebg ) structures present “ forbidden band ” characteristics , siw features high - pass characteristics , so bandpass filters can be composed by combing ebg and siw
本论文提出了两种基片集成波导滤波器结构:将传统的腔体滤波器概念运用于基片集成波导结构,设计出了一种窄带带阻滤波器,对其进行仿真,得到了窄带带阻滤波特性,如相对带宽为1 . 2 % ,最大衰减为48db 。 |
