Stopband-improved substrate-integrated waveguide (SIW) triplexer and triple-band filters are presented based on the novel realization method of coupling topologies composed of common triple-mode resonators coupled with multiple single-mode ones. Thanks to the common triple-mode cavities acting as T-junction proposed in our previous work. the three passbands can be flexibly controlled.... https://www.sukrensi.com/flash-offer-ILOOTPAPERIE-Washi-Tape-best-find/
