摘要
文章应用基模和高次模设计了Ku频段的4阶椭圆函数响应滤波器,并对其仿真和实测结果进行了详细的分析;针对频偏和寄生耦合进行了仿真和结构调整,取得了性能优良的滤波器响应。
In this paper, substrate integrated waveguide （SIW） elliptic filters are proposed by using high mode and fundamental mode to implement negative and positive couplings to generate zeros at finite frequcies. Frequency deviation and spurious coupling are analyzed in detail, and the parameters and configurations are adjusted to solve these problems and good filter responses are obtained.
