Balanced‐to‐unbalanced and balanced‐to‐balanced filtering rat‐race couplers using multilayer substate integrated waveguide cavities

IET Microwaves, Antennas &Propagation, Volume 15, Issue 15, Page 1967-1981, 16 December 2021., 2021
Abstract This study reports a class of balanced‐to‐unbalanced (BTU) and balanced‐to‐balanced (BTB) filtering rat‐race couplers (FRCs) based on multilayer substrate integrated waveguide (SIW) cavities. Input and output ports can perform the functions of balanced and unbalanced terminals to implement various operating states.

Novel balanced single/dual‐band bandpass filters based on a circular patch resonator

IET Microwaves, Antennas &Propagation, Volume 15, Issue 2, Page 206-220, 5 February 2021., 2021
Abstract A new strategy for designing single‐band and dual‐band balanced bandpass filters (BPFs) based on a circular patch resonator is proposed in this study. By altering the output balanced ports of the balanced BPFs to inhibit or transport the TM31 mode of the circular patch resonator under the differential‐mode (DM) excitation, a single‐band or ...
