Single- and dual-band filtering-response power dividers embedded SIW filter with improved output isolation

Abstract Two filtering-response power dividers embedded substrate integrated waveguide (SIW) filter are presented in this paper. By employing different SIW resonators, single- and dual-band filtering response are achieved, respectively. The even- and odd-mode method and the coupled resonator theory...
