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 本論文提出了兩種基片集成波導濾波器結構:將傳統的腔體濾波器概念運用于基片集成波導結構,設計出了一種窄帶帶阻濾波器,對其進行仿真,得到了窄帶帶阻濾波特性,如相對帶寬為1 . 2 % ,最大衰減為48db 。 |

The basic concept of siw is that it use the top and bottom layers of metal together with two row of vias is very small compared with wavelength , the dissipation loss of radiation is very small . it acts like a rectangular waveguide filled with some dielectrics , so components which can be composed by rectangular waveguide can also composed by siw such as antenna , filter , power divider , coupler , resonator 基片集成波導的基本概念是利用基片的上下金屬板和兩排間隔一定距離的金屬孔構成波導的金屬壁,由于每排金屬孔孔間距遠小于波長,因此由縫隙泄漏的能量很小,這相當于內部填充了介質的矩形波導,所以能夠用矩形普通波導實現的結構也都可以用基片集成波導來實現,比如功分器、濾波器、天線、耦合器、振蕩器等。 |
