A Balanced Substrate Integrated Waveguide Phase Shifter with Wideband Common-Mode Suppression

open access: yesMicromachines, 2023
In this paper, a slotted substrate integrated waveguide (SIW) is used to create a balanced phase shifter with wideband common-mode (CM) suppression. Differential-mode (DM) impedance matching and CM suppression are achieved by utilizing the fact that TE20
