Substrate integrated waveguide FPWD with quasi-elliptic response
A novel filtering power divider (FPWD) with a quasi-elliptic response based on the multilayer substrate integrated waveguide is presented. The odd-symmetric fact of the TE102 mode is applied to accomplish two contrary couplings with equal strengths. On the basis of the specially coupling topology, the FPWD can realise quasi-elliptic response. An experimental sample is measured to verify the design methods, and the measured results account with the simulated ones well.
