| Abstract: | 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. |
